I have an array with complex values and I want to normalise the columns. I tried normc(array). But the error is: Data is complex. Is there a way to get around this?

What do you mean by normalise in this context?

sum of the squares of the elements in each column = 1 ( :

@Bonnie: when you tell us what is means to normalize complex numbers, then we can show you how to do it in MATLAB.

The sum of the square of a complex number will still be complex so it can't be 1.

Take each element and multiply by its complex conjugate, so the elements would become real. Square each element and add together. To normalise, divide by sqrt of the sum of the squares.

array = array ./ ( sum( ( array .* conj(array) ).^2 ) ).^0.25

@adam Hi, is that the frobenius norm that you're dividing the matrix with?
Thanks
