Matrix Operators The comma operator separates elements in a row of a matrix A space may be used as well as a comma.

Matrix Operators The semi-colon operator separates rows of a matrix

Matrix Operators The semi-colon operator separates rows of a matrix. May be used to input a rectangular matrix.

Matrix Operators The elements in a rectangular matrix may be accessed individually by their row-column coordinates.

Matrix Transpose Operation Interchanges the rows and columns of a Matrix. The ' Operation in MATLAB If AT = A the matrix is symmetric.
