MATLAB: Transfer functions in the App Designer

app designerMATLABtransfer function

Hi.

I want to create an application in the AppDesigner that serves to automatically generate a transfer function, simply by entering the values of the numerator and denominator on the screen. But, I can't find any information or documentation to guide me in the programming syntax.

Is it possible to make an application like this in the appdesigner and how can I do it?

I understand you want to create an application in which transfer function can be generated automatically as we input numerator and denominator data. Yes, it is possible. Please find following points:

You can explore different ways to get user input and displaying output in App Designer:

You can write callback function to calculate transfer function from the input data:

You can use command “tf”:

Small example

syms s 
Numerator=[1]; 
Denominator=[1 0 1]; 
sys=tf(Numerator,Denominator) 
ex=evalc('sys') 
[a b] = strread(ex, '%s %s', 'delimiter',char(10)); 
num=char(a(2)); 
den=char(a(3));

Now you have the numerator and denominator that can be used in the String of some GUI object like the edit or text

MATLAB: Does the drawfreehand function work with AppDesigner

The 'drawfreehand' function can be used in App Designer by utilizing the 'axes' object:

https://www.mathworks.com/help/matlab/ref/axes.html

The 'axes' object is available in AppDesigner's 'uifigure' starting MATLAB R2018b.

The following commands uses 'drawfreehand' in App Designer:

fig = app.UIFigure; 
ax = axes(fig);
h = drawfreehand(ax);
