Limit on matrix size for Compute.Determinant?
posted

I am using the math library to solve a system of equations.  It works fine within milliseconds for Matrix size of 7 x 7 but when I get to 12 x 12, Compute.Determinant hangs.  Is there something I am missing?

    Hi Daryl,

    I am seeing the same thing.  I'm not sure if this is expected or not but I did notice that the time it takes the Determinant() method to complete increases exponentially as you increase the matrix size.  At 7x7 it took about 0.08 seconds but at 10x10 it took 21 seconds.  I didn't try higher because it took too long.

    I have logged a development issue so our engineers can investigate this.  The ID for the issue is 231201.  I have also opened a private support case for you so that I can link the dev issue to it.  This will allow you to track the status of the dev issue.  The case number is CAS-180493-Z0Z6M0 and you can view it here: https://ko.infragistics.com/my-account/support-activity

    Let me know if you have any questions.
