Description:
+
Demonstrates the use of Matrix Transpose, Matrix Muliplication, and Matrix Inverse functions to apply least squares fitting to input data. Least squares fitting is the procedure for finding the best-fitting curve that minimizes the sum of the squares of the offsets (least square error) from a given set of data.
+
Algorithm:
+
The linear combination of parameters considered is as follows:
+
A * X = B, where X is the unknown value and can be estimated from A & B.
+
The least squares estimate X is given by the following equation:
+
X = Inverse(AT * A) * AT * B
