Error using area plot in App Designer
显示 更早的评论
How can I use area plot in App Desiigner. I am using this code to show the area behide the curve of a function, in order to show the integration area.
This is the code:
f = str2func(app.FuncinEditField.Value)
a = app.aEditField.Value
b = app.bEditField.Value
n = app.nEditField.Value
fplot(app.UIAxes,f, [0,10])
hold(app.UIAxes,"on")
x= linspace(a,b)
y = f(x)
area(app.UIAxes,x,y)
I get this error at area(app.UIAxes,x,y) line: Unable to use a value of type matlab.ui.control.UIAxes as an index.
Thank you for your help

I think you've created a variable with the name area somewhere in your code.
Can you add this code, immediate above the line of code that is calling the area command?
which -all area
whos area
- The which command will tell you if there is another file called area shadowing the built-in copy of area, or if area is the name of a variable in your workspace. Look at the first line of output to see if it says "area is a variable."
- The whos command will tell you about the variable area if it exists in your workspace.
