<br>
When I construct analytical Jacobian matrix it has many small values of order 1E-16.<br>
<br>
How can I remove these values that are less than a given tolerance, let's say 1E-10?<br>

I tried to use MatChop together with MatCopy and MatDuplicate, but none of these functions ignores zeros.<br></blockquote><div><br></div><div>Do you mean that you want to change the sparsity pattern?
