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?

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.

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

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

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.

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...'
