Description

The Constant block generates a specified real or complex value independent of time. The block generates one output, which can be scalar, a vector, or a matrix, depending on the dimensionality of the Constant value parameter and the setting of the Interpret vector parameters as 1-D parameter. If the Interpret vector parameters as 1-D parameter is selected and the Constant value parameter is a column or row matrix, the output is a 1-D array (i.e., a vector) whose elements are the elements of the parameter. Otherwise, the output is a 2-D array (i.e., a matrix) that has the same dimensions as the parameter and whose elements are the parameter elements.

Data Type Support

A Constant block outputs a signal whose numeric type (complex or real) and data type are the same as that of the block's Constant value parameter.

Parameters and Dialog Box

Constant value: The output of the block.
Interpret vector parameters as 1-D: If selected, a column or row matrix value for the Constant value parameter results in a vector output whose elements are the elements of the row or column.
