Code:
function out = rotatex(angle, in)
m=[1 0 0 0; 0 cos(angle) -sin(angle) 0; 0 sin(angle) cos(angle) 0; 0 0 0 1];
out = m*in;
And the call:
Code:
>> out = rotatex(in, pi/4);
? Error using ==> horzcat
CAT arguments dimensions are not consistent.
Error in ==> rotatex at 2
m=[1 0 0 0; 0 cos(angle) -sin(angle) 0; 0 sin(angle) cos(angle) 0; 0 0 0 1];
I've counted the elements, tested the declaration outside the function, and it works. I've removed the minus before the sin. I've declared the rows seperately and tried calling horzcat explicitly and as soon as the trig functions are included it throws a hissyfit..but only when it is called from within the function.
Help much appreciated. In the meantime I'll just head off on a murderous rampage...wanders off muttering expletives.
