Student[LinearAlgebra][MatrixBuilder] - interactive matrix builder

Calling Sequence

MatrixBuilder()    

MatrixBuilder(A,minrc,maxrc,options)

Parameters

A

-

Matrix (optional) Matrix to modify

minrc

-

posint (optional) minimum number or rows and columns

maxrc

-

posint (optional) maximum number of rows and columns

options

-

(optional) equation(s) of the form keyword = truefalse, where keyword is either 'square', 'augmented', 'sqrstatic', or 'augstatic'

Description

• 

The MatrixBuilder command provides an interactive interface for the creation of Matrices up to 5 x 5 in dimension. These matrices can be visualized as augmented matrices. The maplet provides a view of the matrix A, a variable view of A.x or A.x=b in the case of an augmented matrix, and text boxes to enter the entries. When closed, the maplet returns the created matrix.

• 

The maplet has drop-down lists to choose the number of rows and columns of the matrix. The matrix entries are typed in the text boxes.

• 

There are check boxes that determine whether the matrix should be considered square, and/or augmented. If square, the number of columns is controlled by the number of rows. If augmented, the number of columns of the augmented matrix must be greater than one.

• 

The Matrix A can be used to initialize the MatrixBuilder. The parameters minrc and maxrc can only be positive integers from 1 to 5 and provide the minimum and maximum number of rows and columns of the matrix. If A is provided and its dimensions do not satisfy these constraints, an error is returned. Also, if parameters are specified, the first one has to be the matrix A.
