Example: Create a <matrix> from rows
Matrices can be quickly defined by listing row entries within nested <row> components.
Individual entries can be accessed using array notation with the matrix property.
Example: Create a <matrix> from columns
Matrices can be quickly defined by listing column entries within nested <column> components. Individual
entries can be accessed using array notation with the matrix property.
Example: Create a <matrix> of a given size
A <matrix> of a given size can be generated using the numRows and the numColumns attributes. By
default, a zero matrix will be defined; to modify this use the defaultEntry attribute.
Example: Create a <matrix> from user-input rows
This example shows one method of populating the entries of a <matrix> from user-input. See
also, <matrixInput>.
Example: <matrix> addition/ subtraction
The <math> component with the simplify attribute performs matrix addition and subtraction.
Example: <matrix> multiplication
The <math> component, along with both the simplify and expand attributes,
performs matrix multiplication.
Example: Multiplication by a scalar
The <math> component with the simplify attribute performs matrix multiplication by a scalar.
Example: <matrix> from geometry
A coefficient matrix can be constructed from vectors or other
geometric objects by referencing the objects within the <row> or <column>
components. The references should be enclosed in parentheses.
Attribute Example: numRows / numColumns
With numRows and numColumns, a zero matrix of a given size can be defined.
Attribute Example: defaultEntry
Use the defaultEntry attribute to change the prefilled value for a matrix
of a specified size; the default value is .
Property Example: Attributes as properties
The numRows attribute is also accesible as a property.
