%so this is my simply code
r = randi(100,66);
t = (0:1/55:1);
e = exp(2*pi*i*13*t);
t = r.*e % this gives me error why is it and how can fix

@woodson then you have to divide t into 66. as
%if true
t = 0:1/65:1;
To get what you want.

randi(100,66) creates a 66 x 66 matrix of values 1 to 100.
0:1/55:1 is length 56.
When you .* a 66x66 matrix and a 1x56 matrix then what size of output are you expecting?

r = randi(100,66);
t = reshape(0:1/55:1,1,1,[]);
e = exp(2*pi*i*13*t);
t = r.*e;
