MATLAB Online에서 열기 I am trying to use LAPACK 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)...

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...
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
Create the matrix polynomial as a symbolic matrix function f with a0 and A as its parameters. Get syms A [2 2] matrix syms a0 syms f(a0,A) [2 2] matrix keepargs f(a0,A) = a0*eye(2) + A f(a0, A) = a0 I2+A Find the inverse of f using inv. The result is a ...
