how do i set a threshold on the values of the indices in my matrices for my entire code?

Hello,

the code i am using has many matrices. Some of these indices are very small in value. So i want to limit the value i.e. i want to add a threshold to the values of my matrix so that the absolute value is not less than 10e-10

is there a setting or function in matlab that will allow me to do this in one swoop ?

thank you

Try this

M(abs(M)<=1e-9) = 1e-9;

where M is a matrix.

And see Indexing with Logical Values

thank you for your help per isakson

i created a function that employs your approach and called it whenever i needed to clear the noise in a matrix
