This is the Question but when I multiply n with theta it gives any error >> y = sin(n*theta); Error using * Inner matrix dimensions must agree. anyone can help with this.

在 MATLAB Online 中打开

th = linspace(0,2*pi,1000) ;
n = 1:5 ;
y = zeros(length(n),1000) ;
for i = 1:length(n)
    y(i,:) = sin(n(i)*th) ;
end

@ Guillaume yes you are right, but for the beginners to learn coding loop is one of the basic. On using straight away inbuilt functions I feel they cannot learn much of coding.
