Let's say for example you have the vector:
This is basically a 1-by-10 matrix. So,
tries to perform the matrix multiplication operation; but t is 1x10, hence the inner dimensions of t*t are not the same. That is why you get an error.
Now if what you actually want is an array of squares of elements of t, then
is the what you must use. So you equation should be :
y = 1./(t*(3/10^(8*8)*10^(3/2))/2 + 1).^(2/3);
Note: ./, .* and .^ are element-wise operators.
