Hi,
I am very new to the Matlab. I made one function which gives me an array of sinusoids. In arguments, I am providing an array of amplitude, frequency and phase. The other arguments are length and sampling frequency. When I call the function from command line I am getting error mentioned in the title. I have also tried with the .* method.
Can some one guide me the solve the problem?
Thanks.
Error:
Matrix dimensions must agree.
Error in generateSin (line 5)
function [z] = generateSin (a,f, ph,L, Fs)
T = 1/Fs;
tmax = L*T;
t = 0:T:tmax-T;
z = a.*sin (2*pi*t.*f + ph)
end
%command line function call sample : z = generateSin ([3,5,7], [5,10,15], [0,pi/2, pi/6], 1000, 300)

t is a vector of length 1000, a, f and ph are vectors of length 3. What dimension do you expect z to have ?

function [z] = generateSin (a,f, ph,L, Fs)
z = (a(:).*sin (2*pi*(0:L-1)/Fs).*f(:) + ph(:))';
end
