how do i plot sin(2pi*3t) * sin(2pi*15t)?
Ive tried and got this:
y=sin(2*pi*3*t)*sin(2*pi*15*t);
Error using *
Incorrect dimensions for matrix multiplication. Check that the number of columns in the first matrix matches the number of rows in
the second matrix. To perform elementwise multiplication, use '.*'.
>> y=sin(2*pi*3*t.)*sin(2*pi*15*t.);
y=sin(2*pi*3*t.)*sin(2*pi*15*t.);

Error: Invalid expression. When calling a function or indexing a variable, use parentheses. Otherwise, check for mismatched
delimiters.

Hi Jesus,
what they are saying is
% .* for element-by-element multiplication
y=sin(2*pi*3*t).*sin(2*pi*15*t);
