Define strings in MATLAB

I want to define the following as a string in matlab, from s to ).

set(handles.edit,'string','some string')

"I want to define the following as a string in matlab, from s to )."

What is the intended application of this?

[chrisw23]

i.e. (just use double quotes)

handles.edit.string = "some string"

[rmpirooz]

No. I didn't mean this. I want something like following. But Matlab generates error message.

str = 'set(handles.edit,'string','some string')'

I have lots of set and get commands which I need to generate them within a for loop do that I have not to type all of them.

Why don't you explain what you actually want to do? You have described enough for us to know that what you are asking us is a terrible idea, but we don't know what your end goal is.

"I have lots of set and get commands which I need to generate them within a for loop do that I have not to type all of them."

Do NOT do that.

Firstly, (assuming MATLAB graphics object context) both SET and GET accept multiple handles and/or properties. It is often NOT required to call them multiple times, each time to just SET/GET one property. Read the SET/GET documentation to know more:

https://www.mathworks.com/help/matlab/ref/set.html?searchHighlight=vector

Secondly, if for whatever reason you decide to call SET/GET with one handle/property each time, then do NOT create strings of the whole command. That would be a terrible way to write code. Instead you simply put the handles and properties in some arrays and loop over them, e.g.:

P = ["String","Position","Color"];
C = {'Hello world!',[0,0.2,0.5,0.7],'r'};
for k = 1:numel(S)
    set(handles.edit,P(k),C{k})
end

But the best solution is to provide SET/GET with multiple inputs, if that is possible.

Do NOT generate text of the commands you want to run. Ugh.

The code you provided if I have just one edit box.

I have 160 edit boxes (for some reasons I cannot use tables in my GUI) and depending on some conditions some the edit boxes must becom visible and some else invisible.

I want to generate the codes within the for loop so that I have not to generate 160 lines of commands for every conditon.

The problem is that the tag of the edit boxes cannot be generated in a for loop.

[chrisw23]

CtrlName = ["edit1" "edit2" "edit3"] % ...160

P = ["String","Position","Color"];

C = {'Hello world!',[0,0.2,0.5,0.7],'r'};

for k = 1:numel(S)

set(handles.(CtrlName(k)),P(k),C{k})

end

For general advice and examples for how to create a GUI (and avoid using GUIDE), have look at this thread.

Apart from that, you can generate CtrlName with sprintf so you don't have to write them all.

But using an array to store the handles is probably a better solution once you move away from GUIDE.
