changing values in matrix to numbers from particular range

hi, I have matrix X =[1,5,10,14,25;22,30,28,4,2]. I would like to change values of this matrix i this way:

if value is from range: 1:5 change it to 1, 6:10 change it to 2, 11:15 change it to 3, 16:20 change it to 4, 21:25 change it to 5, 26:30 change it to 6.

In result i would like to get matrix [1,1,2,3,5; 5,6,6,1,1].

I try something like this: X(X(1:5)==1, etc... but this does not work well.

Do you have aby ideas?

Thanku you in advance.

X = [1,5,10,14,25;22,30,28,4,2];
display(X);

X = 2×5

1 5 10 14 25 22 30 28 4 2

X(X >= 1 & X <= 5) = 1;
X(X >= 6 & X <= 10) = 2;
% and so on for the rest of the ranges
display(X);

X = 2×5

1 1 2 14 25 22 30 28 1 1
