can anyone help me fixing this code
n = 0:1:50;
y = (0.3)^(n)*cos(2*pi*0.05)*heaviside(n);
Error using ^ (line 51)
Incorrect dimensions for raising a matrix to a power. Check that the matrix is
square and the power is a scalar. To perform elementwise matrix powers, use '.^'.
and if i put the point it shows
n = 0:1:50;
y = (0.3).^(n)*cos(2*pi*0.05)*heaviside(n);
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 '.*'.

Change * to .* in all the places.
