Ok so now I have:

function [cosine] = james(x)
[cosine]=euler(x);
function [cosine]= euler(x)
cosine = exp.^((1i)*x)-1i*sin(x);
end

end

Matlab says that to compute

[cosine]=euler(0:pi/4:2*pi)

i need to have exp as exp.^ and not exp^ but this still causes an error of :

Error using ^
Inputs must be a scalar and a square
matrix.
To compute elementwise POWER, use POWER
(.^) instead.

Error in euler (line 3)
cosine =e^(1i*x)-1i*sin(x);


What exactly am doing wrong? I put the exp.^ just as matlab said but Matlab still says there is the same error!
