How do you square in MATLAB?

For example, you might write x. ^2 in another way, using x. *x. This would effectively square every element in the vector x.

How to do square root in MATLAB?

B = sqrt( X ) returns the square root of each element of the array X . For the elements of X that are negative or complex, sqrt(X) produces complex results.

How do you write sin 2 in MATLAB?

MATLAB syntax only supports the sin(x)^2 (or sin(x). ^2 if you want element-wise) version.

How do you do sum of squares in MATLAB?

[ s , n ] = sumsqr( x ) takes a matrix or cell array of matrices, x , and returns the sum, s , of all squared finite values in x , and the number of finite values, n . If x does not contain finite values, the sum returned is 0.
