of system of linear equations we’ll find X such that (AX-B) is minimum which means each element of E (=AX-B) is very close to 0. Now our objective will be minimizing the (transpose(E)E). To minimize f(X) we will differentiate f(X) w.r.t. X and set it equal to 0. Then calculate the value of X. Note:
