Description

The PS Sum of Elements block calculates the sum of elements of a vector or matrix input physical signal:

y=sum(u)

where:

  • y is the physical signal at the output port O.

  • u is the physical signal at the input port I.

Ports

Input

expand all

Input physical signal specified as a row or column vector or a matrix.

The port name is not visible in the block icon, but you can see this name in the underlying source file by clicking the Source code link in the Description tab of the block dialog box.

Programmatic Use

Port: I

Output

expand all

Output physical signal. If the input signal is a vector, then the output signal is a scalar. If the input signal is a matrix, then by default the block computes the column-wise sum for each dimension. For example, if the input signal is a two-dimensional matrix, then by default the output signal is a vector. If you select the Sum all elements check box, then the output signal is a scalar.

The port name is not visible in the block icon, but you can see this name in the underlying source file by clicking the Source code link in the Description tab of the block dialog box.

Programmatic Use

Port: O

Parameters

expand all

If the input signal is a matrix, then by default the block computes the column-wise sums of elements for each dimension. To sum all the elements of the matrix, select the Sum all elements check box.

Programmatic Use

Parameter: sumAll
Values: "true" | "false"

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.

"fl_lib/Physical Signals/Functions/PS Sum of Elements"

Example: add_block("fl_lib/Physical Signals/Functions/PS Sum of Elements","myModel/myBlock",MakeNameUnique="on")

For information about programmatic access to individual block parameters, see the Programmatic Use section of parameter descriptions on this page.
