Detailed explanation-1: -In mathematics, an inverse is a function that serves to “undo” another function. That is, if f(x) produces y, then putting y into the inverse of f produces the output x. x . A function f that has an inverse is called invertible and the inverse is denoted by f−1.
Detailed explanation-2: -Y = inv( X ) computes the inverse of square matrix X . X^(-1) is equivalent to inv(X) . x = Ai¯s computed differently than x = inv(A)*b and is recommended for solving systems of linear equations.
Detailed explanation-3: -An inverse function essentially undoes the effects of the original function. If f(x) says to multiply by 2 and then add 1, then the inverse f(x) will say to subtract 1 and then divide by 2. If you want to think about this graphically, f(x) and its inverse function will be reflections across the line y = x.
