- Minus is one of the four basic operations of arithmetic.
- Minus operation is the opposite operation of Add.
- Matrix minus is the basic operation of subtracting two matrices with the corresponding entries.
- Two matrices must have an equal number of rows and columns.
- The minus of matrices A and B is denoted by Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle A-B= \begin{bmatrix} a_{11} & a_{12}&\cdots & a_{1n} \\ a_{21}& a_{22}& \cdots & a_{2n} \\ \vdots & \ddots & \vdots \\ a_{m1} & a_{m2}& \cdots & a_{mn} \end{bmatrix} -\begin{bmatrix} b_{11} & b_{12}&\cdots & b_{1n} \\ b_{21}& b_{22}& \cdots & b_{2n} \\ \vdots & \ddots & \vdots \\ b_{m1} & b_{m2}& \cdots & b_{mn} \end{bmatrix} = \begin{bmatrix} a_{11}-b_{11} & a_{12}-b_{12}&\cdots & a_{1n}-b_{1n} \\ a_{21}-b_{21}& a_{22}-b_{22}& \cdots & a_{2n}-b_{2n} \\ \vdots & \ddots & \vdots \\ a_{m1}-b_{m1} & a_{m2}-b_{m2}& \cdots & a_{mn}-b_{mn} \end{bmatrix}}
- Suppose the number of rows in the first matrix is more than the second matrix,this function will return the extra row entries with the same number.
- Suppose the number of rows in the second matrix is more than the first matrix ,the extra row values of the second matrix will be ignored.
