In my program I use inverse of the matrix like below. But getting this error "Matrix is close to singular or badly scaled. Results may be inaccurate. RCOND = 5.872930e-17".
a = inv(matrix);
The result of inverse matrix has to be used in my program

The error message tells you, that your matrix is near to be singular. Then it cannot be converted reliably, because the result is dominated by rounding errors.
This means, that there is a mathematical problem, which is not related to Matlab.
