how to do normalization of a matrix

I have a matrix wity dimension 100 by 50. Now i want to normalize the matrix by doing normaization of each column. I want to normlaize each column separately to do normalization

You can use the function normalize and specify which dimension you want to normalize.

From the documentation

"N = normalize(A) returns the vectorwise z-score of the data in A with center 0 and standard deviation 1.

If A is a vector, then normalize operates on the entire vector.

If A is a matrix, table, or timetable, then normalize operates on each column of data separately.

If A is a multidimensional array, then normalize operates along the first array dimension whose size does not equal 1. "

I want to normalioze each column by dviding its maximum value and continue for all columns

[Mohammad Sami]

You can just divide your matrix with the column max in that case.

b = a ./ max(a);

i have solved it by myself

it will be

b=(a./max(a, [ ] ,1));

It is exactly the same as what Sami suggested.

yes.but it would not give me the all normalized columns
