MATLAB: Can Stateflow use Microsoft Excel data for simulation input

importing excel dataMATLABsimulinkstateflowstateflow diagram

I want to input data that I have in excel into Stateflow and use this data to run simulations in Stateflow. The data in excel is a large amount of values used for the different variables in my Stateflow chart.

Import the data into MATLAB using import wizard or xlsread. You can then use it as input(s) for your Simulink/Stateflow model with the Signal Builder or From Workspace blocks. Have a look at Data Import and Export in the MATLAB documentation.

MATLAB: Excel Chart with 2 X-axis through matlab

I have found the solution with

Excel.ActiveChart.ChartType = 65; 
can not make 2 X-axis . I did that on ChartType = 73 and worked very well
Here the list of chart type

hier ist mein end Code

Excel = actxserver('excel.application');

Hi Murali,

using a sample time of 0.01s for your model lets you only generate pulses with a multiple of the basic sample time(0.01 / 0.02 / 0.03) If you want to generate a pulse of 0.025 you have to increase your sample time to e.g. 0.001s
