to invert a matrix in Fortran through mex. Depending on the matrix dimension Matlab crashes. E.g. for Hin=diag(1:3);[T1]=TestInvMex(int32(1),Hin) gives correct answer. Hin=diag(1:6);[T1]=TestInvMex(int32(1),Hin) crashes. Matlab version 2012b on linux. My code TestInv...
Hello, I want to know how to write matlab code to obtain lower triangle matrix or inverse matrix by approaching from deep neural network if the input is symmetric and positive-definite matrix. 댓글 수: 0 댓글을 달려면 로그인하...
inverse matrix in mexFunctionI found the problem now. The code that I pasted below did not work as I forgot to change the 'int' in sizeof to 'size_t'. Thank you guys for pointing out the errors!!! ;) You saved my day!the
Open in MATLAB Online Hi, I am trying to find the matrix X, which minimizes the objective function. However, I see the following error: Error using inv Invalid data type. Input matrix must be double or single. Error in t2 (line 11) prob.Objective=trace(R - R*X'*inv(X*R*X' + s...
1. Matlab code to find the inverse of the above matrix; Consider matrix u ; u=[ 4 7 3; 7 3 2;2 1 8] v=inv(u) To obtain the inverse of the matrix there is one condition, the input matrix must be ‘square matrix’. otherwise, it will give the error. let see one example of...
