Bug: input checking gives misleading message

[cldonovan]

What Happened?

If a user specifies a medium.alpha_coeff that contains imaginary components, the error message received is medium.alpha_power must be a real number between 0 and 3. This is due to a typo in kspaceFirstOrder_inputChecking.m on line 216.

Appears the code should read if ~isreal(medium.alpha_power) || (medium.alpha_power >= 3 || medium.alpha_power < 0) instead of if ~isreal(medium.alpha_coeff) || (medium.alpha_power >= 3 || medium.alpha_power < 0)

Error messages

medium.alpha_power must be a real number between 0 and 3

How Can We Reproduce?

Run any example code, setting medium.alpha_coeff equal to a complex value or matrix.
