Problem in Signal Builder

Hi... I like import files from Microsoft Excel... I already read this: http://www.mathworks.com/help/toolbox/simulink/gs/bsmigir.html

But in step 4, when i click in File, don't appear "Import from File". Why?

Answer 1

[Fangjun Jiang]

Are you sure? Please not to click the menu "File" in your Simulink model. You need to double click the "Signal Builder" block and then click the menu "File" from the pop-up GUI.

Yes, see the print: http://img821.imageshack.us/img821/4963/filew.png

What version of Matlab/Simulink? type "ver" in Matlab command window to find out.

[Nuno]

MATLAB Version 7.9.0.529 (R2009b)

[Fangjun Jiang]

That's weird. Try to contact Matlab tech support. Is your computer a Mac or PC? It shouldn't matter though, right?

[Walter Roberson]

Gotta be PC; Mac would use apple-Q for Quit, not control-W .

[Fangjun Jiang]

Not sure if this is related. Try to close other figure window if you have any.

[Nuno]

I closed but nothing...

Is PC... I don't understand :(

It's very important...

[Fangjun Jiang]

Re-start Matlab. If no luck, definitely contact Matlab tech support.

[Nuno]

Fangjun Jiang don't appear...

Don´t appear "Import from File"... Any ideia to make this graph: http://img268.imageshack.us/img268/7779/graphap.png

Answer 4

[Guy Rouleau]

Import from file is a feature introduced in R2010b. If you have an older release, you need to upgrade

[Nuno]

Is there any way I can achieve this without installing another version of Matlab?

[Arnaud Miege]

Guy's correct, see release notes for R2010b (http://www.mathworks.com/help/releases/R2011a/toolbox/simulink/rn/bsjn1am-1.html). A workaround is to import the data from Excel into MATLAB using the import wizard or xlsread, and then the Signal Builder with the data from the workspace.

[Nuno]

How i use import wizard or xlsread?

[Fangjun Jiang]

My mistake. Guy is right. The "Import form file" item under menu "File" in Signal Builder GUI is only available since 2010b.

[Fangjun Jiang]

run the uiimport command in Matlab. type "help xlsread" to get the syntax of using xlsread()

[Arnaud Miege]

Have a look at the MATLAB and Simulink tutorials on http://www.mathworks.com/academia/student_center/tutorials/. You should also read the "Data Import and Export" section of the MATLAB documentation (http://www.mathworks.com/help/releases/R2011a/techdoc/import_export/ug_intropage.html).

[Nuno]

But to transfer values from Excel to simulink and contruct a graph?

[Arnaud Miege]

You haven't read what I said: you don't transfer values from Excel to Simulink. You import the data from Excel into MATLAB and then read the data from the MATLAB workspace in the Signal Builder block. Read through the documentation and the tutorials I suggested.

Answer 5

[Fangjun Jiang]

So there is no problem on Simulink Signal Builder block. You want to create a curve like you have show in the Signal Builder block. Assume you have the data points for that curve in an Excel file, you can follow the advice provided to import those data points into Matlab workspace, then you'll have the x and y values for that curve. Go to Signal Builder block GUI, click menu 'Signal'>'New'>'Custom...'
