MATLAB: How to see the signal dimensions of simulink blocks

simulink

my model shows the error " Error in port widths or dimensions".so i wants to verify the dimensions during the simulation time

In 2013b version:

To determine the dimension of output signal from a Simulink block programmatically, please follow these steps:

1. Get the port handles of the required Simulink block. To do this, you can use the "Port Handles" Parameter.

For example:

Handles =  get_param('test/Add', 'PortHandles');

This will return a struct. You can isolate Outport handles by accessing it like this :

OutHandles = Handles.Outport

2. You can now use the "CompiledPortDimensions" on the corresponding handle to get the dimensions.

For example:

Dimensions = get_param(Outport, 'CompiledPortDimensions');

Hi Maximum,, the error is .. input signal to reshape is a signal of [61 x 1] where as the reshape block needs a matrix of [4096x1].

input should be a matrix of 4096x1 or 64x64
