MATLAB: How to replace numbers that are ‘greater than or equal to’ a specific number and replace them with zero’s.

if statementloopmatrix

I know this sound quite straight forward but I'm confused with the 'greater than or equal to' part.

If I have a matrix of random numbers, how can i find all the numbers that are 'greater than or equal to' 99 and replace them with zero's.

Thank you

a(a>=99)=0

MATLAB: Replace ‘greater than’ values in a matrix

M - your matrix

M(M > a) = b;

MATLAB: Histogram: ‘Greater than’ bin

Add -Inf as the first element of the edges vector and/or Inf as the last element.

>> x = randn(1, 1e6);
>> h = histogram(x, [-Inf -2:0.25:2 Inf]);
>> tooSmallH = h.Values(1)
>> tooSmallX = nnz(x < -2)
>> tooLargeH = h.Values(end)
>> tooLargeX = nnz(x > 2)

The two variables whose names start with tooSmall should have the same value, as should the two variables whose names start with tooLarge.
