I'm using matlab 2016. when I want to normalize the matrix, the only available syntax is normr and normc. While on the matlab website page there is a normalize syntax. why is there no normalize syntax in my matlab? Then how to normalize matlab manually?

The command normalize introduced in MATLAB 2018a version, as per your statment you are using MATLAB2016 version. Upgrade your MATLAB version or you could write your own normalize function as per your requirements

If you just want to normalize the array such that its extrema correspond to [0 1], then for a given array A:
mn = min(A(:));
mx = max(A(:));
B = (A-mn) ./ (mx-mn);
If you have IPT, you can also use the short syntax of the mat2gray() function:
B = mat2gray(A);
