[additive color model]{#additive-color-model} : A way to represent colors as the sum of contributions from primary colors such as red, green, and blue.
[argument]{#argument} : A value given to a function or program when it runs. The term is often used interchangeably (and inconsistently) with parameter.
[assertion]{#assertion} : An expression which is supposed to be true at a particular point in a program. Programmers typically put assertions in their code to check for errors; if the assertion fails (i.e., if the expression evaluates as false), the program halts and produces an error message. See also: invariant, precondition, postcondition.
[assign]{#assign} : To give a value a name by associating a variable with it.
[body]{#body} : (of a function): the statements that are executed when a function runs.
[call stack]{#call-stack} : A data structure inside a running program that keeps track of active function calls.
[case-insensitive]{#case-insensitive} : Treating text as if upper and lower case characters of the same letter were the same. See also: case-sensitive.
[case-sensitive]{#case-sensitive} : Treating text as if upper and lower case characters of the same letter are different. See also: case-insensitive.
[comment]{#comment}
: A remark in a program that is intended to help human readers understand what is going on,
but is ignored by the computer.
Comments in MATLAB start with a % character and run to the end of the line;
[compose]{#compose}
: To apply one function to the result of another, such as f(g(x)).
[conditional statement]{#conditional-statement} : A statement in a program that might or might not be executed depending on whether a test is true or false.
[comma-separated values]{#comma-separated-values} : (CSV) A common textual representation for tables in which the values in each row are separated by commas.
[default value]{#default-value} : A value to use for a parameter if nothing is specified explicitly.
[defensive programming]{#defensive-programming} : The practice of writing programs that check their own operation to catch errors as early as possible.
[delimiter]{#delimiter} : A character or characters used to separate individual values, such as the commas between columns in a CSV file.
[documentation]{#documentation} : Human-language text written to explain what software does, how it works, or how to use it.
[empty string]{#empty-string} : A character string containing no characters, often thought of as the "zero" of text.
[encapsulation]{#encapsulation} : The practice of hiding something's implementation details so that the rest of a program can worry about what it does rather than how it does it.
[floating-point number]{#floating-point-number} : A number containing a fractional part and an exponent. See also: integer.
[for loop]{#for-loop} : A loop that is executed once for each value in some kind of set, list, or range. See also: while loop.
[function call]{#function-call} : A use of a function in another piece of software.
[in-place operators]{#in-place-operators}
: An operator such as += that provides a shorthand notation for
the common case in which the variable being assigned to
is also an operand on the right hand side of the assignment.
For example, the statement x += 3 means the same thing as x = x + 3.
[index]{#index} : A subscript that specifies the location of a single value in a collection, such as a single pixel in an image.
[inner loop]{#inner-loop} : A loop that is inside another loop. See also: outer loop.
[integer]{#integer} : A whole number, such as -12343. See also: floating-point number.
[invariant]{#invariant} : An expression whose value doesn't change during the execution of a program, typically used in an assertion. See also: precondition, postcondition.
[library]{#library} : A family of code units (functions, classes, variables) that implement a set of related tasks.
[loop body]{#loop-body}
: The set of instructions appearing between the line with the for keyword and
the line with the end keyword.
[loop variable]{#loop-variable} : The variable that keeps track of the progress of the loop.
[outer loop]{#outer-loop} : A loop that contains another loop. See also: inner loop.
[parameter]{#parameter} : A variable named in the function's declaration that is used to hold a value passed into the call. The term is often used interchangeably (and inconsistently) with argument.
[pipe]{#pipe} : A connection from the output of one program to the input of another. When two or more programs are connected in this way, they are called a "pipeline".
[postcondition]{#postcondition} : A condition that a function (or other block of code) guarantees is true once it has finished running. Postconditions are often represented using assertions.
[precondition]{#precondition} : A condition that must be true in order for a function (or other block of code) to run correctly.
[regression]{#regression} : To re-introduce a bug that was once fixed.
[RGB]{#rgb} : An additive model that represents colors as combinations of red, green, and blue. Each color's value is typically in the range 0..255 (i.e., a one-byte integer).
[silent failure]{#silent-failure} : Failing without producing any warning messages. Silent failures are hard to detect and debug.
[size]{#size}
: An array's dimensions, represented as a vector.
For example, a 5×3 array's size is (5,3).
[slice]{#slice} : A regular subsequence of a larger sequence, such as the first five elements or every second element.
[stack frame]{#stack-frame} : A data structure that provides storage for a function's local variables. Each time a function is called, a new stack frame is created and put on the top of the call stack. When the function returns, the stack frame is discarded.
[standard input]{#standard-input} : A process's default input stream. In interactive command-line applications, it is typically connected to the keyboard; in a pipe, it receives data from the standard output of the preceding process.
[standard output]{#standard-output} : A process's default output stream. In interactive command-line applications, data sent to standard output is displayed on the screen; in a pipe, it is passed to the standard input of the next process.
[stride]{#stride} : The inter-element increment of a regularly-spaced list of integers, as generated by MATLAB's colon operator.
[string]{#string} : Short for "character string", a sequence of zero or more characters.
[syntax error]{#syntax-error} : CHECKME: a programming error that occurs when statements are in an order or contain characters not expected by the programming language
[test oracle]{#test-oracle} : A program, device, data set, or human being against which the results of a test can be compared.
[test-driven development]{#test-driven-development} : The practice of writing unit tests before writing the code they test.
[type]{#type} : CHECKME The classification of something in a program (for example, the contents of a variable) as a kind of number (e.g. floating-point, integer), string, or something else.
[while loop]{#while-loop} : A loop that keeps executing as long as some condition is true. See also: for loop.
