+
+    Given two points (x1, y1) and (x2, y2), this function calculates the coefficients 'a' and 'b'
+    for a tanh function of the form y = 0.5 * (tanh(a * (x - b)) + 1) that passes through these points.
+
+    The derivation is as follows:
+
+    1. Start with the equation of the tanh function:
+       y = 0.5 * (tanh(a * (x - b)) + 1)
+
+    2. Rearrange the equation to isolate tanh:
+       tanh(a * (x - b)) = 2*y - 1
+
+    3. Take the inverse tanh (or artanh) on both sides to solve for 'a' and 'b':
+       a * (x - b) = artanh(2*y - 1)
+
+    4. Plug in the points (x1, y1) and (x2, y2) to get two equations.
+       Using these, we can solve for 'a' and 'b' as:
+       a = (artanh(2*y2 - 1) - artanh(2*y1 - 1)) / (x2 - x1)
+       b = x1 - (artanh(2*y1 - 1) / a)
+
+    Parameters
+    ----------
+    x1
+        x-coordinate of the first point.
+    x2
+        x-coordinate of the second point.
+    y1
+        y-coordinate of the first point (should be between 0 and 1).
+    y2
+        y-coordinate of the second point (should be between 0 and 1).
+
+    Returns
+    -------
+    a
+        Coefficient 'a' for the tanh function.
+    b
+        Coefficient 'b' for the tanh function.
