I have a 48X128 matrix. I want to normalize each row to the maximum value in that row. What function will achieve this?

Ran in:
Use normalize() to normalize each row or use simple matrix operation to obtain the values of matrix elements to be between [0 .. 1]:
A = randi(10, 7 , 5) % Data
A = 7×5
8 8 2 7 10 3 2 9 10 7 2 10 1 6 10 2 2 10 5 6 8 9 7 5 8 2 3 9 3 8 2 7 3 6 10
An = normalize(A,2) % Normalize each row
An = 7×5
0.3333 0.3333 -1.6667 0 1.0000 -0.8979 -1.1785 0.7857 1.0663 0.2245 -0.8907 0.9845 -1.1251 0.0469 0.9845 -0.9045 -0.9045 1.5076 0 0.3015 0.3956 1.0550 -0.2638 -1.5825 0.3956 -0.9258 -0.6172 1.2344 -0.6172 0.9258 -1.1217 0.4362 -0.8101 0.1246 1.3710
ANor = A./max(A(1:end,:)) % Normalize wi.r.t. max value of each row
ANor = 7×5
1.0000 0.8000 0.2000 0.7000 1.0000 0.3750 0.2000 0.9000 1.0000 0.7000 0.2500 1.0000 0.1000 0.6000 1.0000 0.2500 0.2000 1.0000 0.5000 0.6000 1.0000 0.9000 0.7000 0.5000 0.8000 0.2500 0.3000 0.9000 0.3000 0.8000 0.2500 0.7000 0.3000 0.6000 1.0000

the normalize function defaults to normalising by 'zscore' . For other options, see the documentation section on method.
