Reducing every value of a matrice every time by the same value

Hello, I am new at matlab and I have a question. Is it possible to reduce every single value of a nx2 matrix by the same amount until all values are zero? Maybe in a for loop?

Of course. Math operations by constants on arrays work on the entire array by default.
Of course, hitting zero exactly would require a specific value that is evenly divisible into the original value without rounding so it may or may not work out exactly depending upon the values in the array.
Or, of course, if the values in the array aren't the same, you'd have to compute that difference by dividing by the number of iterations and then do array addition/subtraction which is also array-wide.
Again, floating point rounding can make hitting exactly zero tricky...

This might be what you want, but as @Scott MacKenzie says you've left a lot of problem details and issues for us to guess,
while any(matrix(:)>0)
matrix=max(matrix-something,0);
end

Oh. I see I just duplicated Matt's answer that was already there...I had just read the comments before.
