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
