@@ -32,7 +32,7 @@ As general remarks, one should keep in mind that:
 - Some clobal variables have been added as a new (last) argument to the function they appear in.
 - When a function is defined on Matlab with multiple outputs, as in `[y1, y2] = f(x)`, it will output only `y1` if called without assignment, as in `f(3)`, or if called with a one-length assignment, as in `a = f(3)`. In order to receive the full output, one must assign two variables to the left side of the assignment operator, as in `[a, b] = f(3)`. rBAPS Functions that might be affected by this behavior include `etsiParas`.
