Command Reference : Matrix Language Reference
Syntax: @inverse(m)
Argument: square matrix or sym, m
Return: matrix or sym
Returns the inverse of a square matrix object or sym. The inverse has the property that the product of the source matrix and its inverse is the identity matrix. The inverse of a matrix returns a matrix, while the inverse of a sym returns a sym. Note that inverting a sym is much faster than inverting a matrix.
matrix m2 = @inverse(m1)
sym s2 = @inverse(s1)
sym s3 = @inverse(@implode(m2))
