compstatslib interactive_matrix_inverse() function

Description

Interactive function that allows one to *manipulate* a matrix inversion.

Usage

interactive_matrix_inverse(x1_init=1, y1_init=2, x2_init=2, y2_init=1)

After running the function, the user can click on the gear icon in the top-left corner of the plot area.
A window with four slider bars will pop up, allowing the user to change the value of the 4 parameters.

Arguments

x1_init	The first row (or column) vector of matrix A. This parameter is set to 1 by default.
y1_init	The second row (or column) vector of matrix A. This parameter is set to 2 by default. The area of the parallelogram resulting from these two vectors is the determinant of matrix A.
x2_init	The first row (or column) vector of the inverse matrix A^(-1). This parameter is set to 2 by default.
y2_init	The second row (or column) vector of the inverse matrix A^(-1). This parameter is set to 1 by default. The area of the parallelogram resulting from these two vectors is the determinant of the inverse matrix A^(-1).
