FUNCTIONsolve

RETURN TYPEboolean

Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Solves one or more linear systems or least-squares problems.

The function cv::solve solves a linear system or least-squares problem (the latter is possible with SVD or QR methods, or by specifying the flag #DECOMP_NORMAL ):

\texttt{dst} =  \arg \min _X \| \texttt{src1} \cdot \texttt{X} -  \texttt{src2} \|

If #DECOMP_LU or #DECOMP_CHOLESKY method is used, the function returns 1 if src1 (or \texttt{src1}^T\texttt{src1} ) is non-singular. Otherwise, it returns 0. In the latter case, dst is not valid. Other methods find a pseudo-solution in case of a singular left-hand side part.

Note: If you want to find a unity-norm solution of an under-defined singular system \texttt{src1}\cdot\texttt{dst}=0 , the function solve will not do the work. Use SVD::solveZ instead.

2 available overloads

solve(src1: Mat, src2: Mat, dst: Mat): boolean;

solve(src1: Mat, src2: Mat, dst: Mat, flags: number): boolean;

src1: input matrix on the left-hand side of the system.
src2: input matrix on the right-hand side of the system.
dst: Output destination, filled by the native operation. output solution.
flags: solution (matrix inversion) method (#DecompTypes)

Returns

The boolean result.
