Matlab can solve these equations approximately with the command c = A \ y. The solution c is called the “least squares” solution for reasons that we will describe later in the course. To illustrate an application involving this use of a rectangular matrix suppose that we wish to fit the three points (0,3), (2,5), and (4,6) with a straight line.

Thus, in order to optimize the performance of applications, we present in Section 3.2 a quite fast solution of type (4), and in Section 3.3 a solution of type (5) whose computational cost is similar to that of (3), which has the advantage of being fast while providing a suitable least-squares solution in all cases, even if the system is rank ...

The solution must be in Matlab .mat format and should contain a variable called “solution”. The variable “solution” could have the following format: A matrix with 4 columns, representing the epochs, the latitude (in degrees), the longitude (in degrees) and the height (in meters).

At this point, our undetermined coefficients, should satisfy the matrix equation We seek a least squares solution to this equation. We use a modification of the svd command which produces a smaller singular value decomposition, although not always the compact one. (S will always be square, but some of the diagonal entries may be 0.)

Least Squares. If A is an m by n rectangular matrix with m >= n and if c is a vector with n components then A c = y can not usually be solved exactly. Matlab can solve these equations approximately with the command c = A \ y. The solution c is called the “least squares” solution for reasons that we will describe later in the course.

This problem appears frequently in very diverse applications and its solution is well known, e.g., see [4]. Briefly stated, the least squares solution is. where X is an (m x 1) vector produced by the concatenation of the xi’s and W is an (m x n) matrix produced by the concatenation of …
