I want to give Excel sheet input to Transfer Function Simulink Block

Hello

As mentioned,

I have an excel sheet as well as .mat file any of them one can be used for below scenerio.

It is having one parameter with almost 20000 different values.

So how can I give these value to Transfer Function block?

I tried with 1-D Lookup Table but it is showing Error Msg as:

Error in port widths or dimensions. Output port 1 of 'LPF1/In1' is a one dimensional vector with 20618 elements.

Error in port widths or dimensions. Invalid dimension has been specified for input port 1 of LPF1/TransferFunc.

Please let me know for brief.

Thank you

hello

what kind of parameters are you trying to transfer to the Transfer Function Simulink Block ?

Transfer Function Simulink Block expect you to give numerator and denominators coefficients of the TF

Hello @Mathieu NOE

I set the values for TF as

Numerator Coefficients: [10.5]

Denominator coefficients : [1 10.0531]

IMG.

at the In1 Input Port 1. I am planning to give sort of set of data inputs/.mat/.excel. I am not sure how I can pass it.

.mat file IMG.

Thank you

So you have your TF block aleady set

if i understand correctly you simply have to take your time and data arrays as input of the TF block

simply load in your workspace time and data and use "from Workspace" Simulink Block
