Walter Roberson on 1 Feb 2021. Sure you can define them. You can create MATLAB Function Blocks. Or use Gain blocks. You could probably even create Subsystems if you want them to appear to be library blocks.

MATLAB does not have ++ or += or -- or -= or *= or /= or %= and is not expected to get any of those for some time (if at all.) I think if you look back at your Java you will find it was ++ rather than += that you were using for incrementing. Hello all, First of all, I would like to say thanks for all your help.This should perfectly replicate the centre 7x7 pixels from the matlab function if you use the correct 0.5 start mapping as well. Then add the border after interpolating to create the 9X9 image. Or edit your loop so it does not interpolate on the edge pixels (only the middle 7X7) and just repeats the closest pixel for the edge.Y = acos (X) returns the Inverse Cosine (cos -1) of the elements of X in radians. The function accepts both real and complex inputs. For real values of X in the interval [-1, 1], acos (X) returns values in the interval [0, π]. For real values of X outside the interval [-1,1] and for complex values of X, acos (X) returns complex values. Data is inferred as a variable size matrix,...
