bins = discretize(TheMatrix, Vector_of_Breakpoints);
It does not matter how many entries are in Vector_of_Breakpoints as long as there are at least two values and the vector is sorted.
The result would be a matrix the same size as TheMatrix.
If any values are less than Vector_of_Breakpoints(1) or greater than Vector_Of_Breakpoints(end) then the corresponding output will be 0.
Note that by default the maximum bin number will be length(Vector_of_Breakpoints)-1 with the values exactly equal to Vector_of_Breakpoints(end) being placed together with the previous bin. There are options to change how the boundaries work.
