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 or 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.

Options
|
|
•
|
The option 'square' = truefalse controls the default value of the square check box.
|
•
|
The option 'augmented' = truefalse controls the default value of the augmented check box. If 'augmented'= true, A is provided and is a one column matrix, an error is returned.
|
•
|
If the option 'sqrstatic'= true then the square check box in the maplet is disabled, otherwise it is enabled.
|
•
|
If the option 'augstatic'= true then the augmented check box in the maplet is disabled, otherwise it is enabled.
