Matlab Functions and GUI

I keep getting an error saying that I'm "Out of memory. The likely cause is an infinite recursion within the program.".

I'm trying to incorporate a function with a Matlab GUI.

function [num] = fahrenheit(x, totype)
%UNTITLED2 Summary of this function goes here
%   Detailed explanation goes here


if fahrenheit(x,'Celsius to Fahrenheit')
    
    num =(x * 9/5) + 32;
   
end


end

And this is the Callback function within the GUI.

function ConvertButtonPushed(app, event)
            value = app.DirectionDropDown.Value;
            conversion = app.ValueEditField.Value;
            
            
            
            
             [f] = fahrenheit(conversion,value);
             app.ConversionOutputLabel.Text = ['Conversion Output = ' num2str(f)];
end

You have a recursive function that doesn't get anywhere: if fahrenheit(x,___). At that point the function calls itself. Before trying to incorporate a function in a GUI, you need to make sure it works in the first place.

You probably mean to compare the second input to a specific text. You should use the strcmp function to do that.
