Hello everyone,
I am trying to join two strings and then I need to have it as character and remove all the single or double inverted commas on it.
Also, how to give one input as variable.
for example.
"obj.UI.knob_" + "4" + ".Value"
here "4" is variable and it should change.
At the end I should have- obj.UI.knob_4.Value and not "obj.UI.knob_4.Value" i.e I dont need inverted commas.
I request to pleae help in removing the inverted commas, and how to pass variable in it.
Thanking you,
Kind regards

"I request to pleae help in removing the inverted commas"
The "inverted commas" are not a part of the text, there are purely an artifact of the display routine. You are confusing how data is displayed in the command window with the data itself.

That's how strings will be displayed if you directly type variable holding the string in command window. If you just want to display string without commas, you can use disp function.

Hi @Paramjit Yadav
1st - use a single 'postrophe': ' instead of "
I have created a simple function that returnes the value of a Knob.
Add this function to your app
function out = ret_Knob_value(obj,num)
eval(['out = obj.Knob' ,num2str(num), '.Value;']);
Good luck!

@Matlab Pro
Thank you so much for answering.
But I need 'out = obj.Knob' ,num2str(num), '.Value' to displayed as
out = obj.Knob4.Value. without inverted comas. Since I have prepared app without using app tool bar. Hence I need it to change values.
Here I get 'out = obj.Knob4.Value' i.e with single inverted commas. I dont wantt this single inverted commas as well in the end.
Thanking yoiu,
Kind regards
