https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Which-function-could-solve-linear-least-square-with-inequality/m-p/1169216#M28434 <P>I want to solve X in a linear system A*X=B with constraints that all elements in X are non-negative. It is a Non-negative Least Squares (NNLS) problem. Do you know which function can be used for it? I tried the function&nbsp;trnlspbc_solve (nonlinear least squares problem with linear constraints), but it does not work well for this linear least square problem. Any ideas?&nbsp;</P> Wed, 13 Mar 2019 21:54:34 GMT Guo__Qiandong 2019-03-13T21:54:34Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Which-function-could-solve-linear-least-square-with-inequality/m-p/1169216#M28434 <P>I want to solve X in a linear system A*X=B with constraints that all elements in X are non-negative.
