Multiple prompt/input with inputdlg according to a value

Hi everybody, I am at the "visual" stage of my program and I want to simplify the input process.

The program works with a variable amount of colors which changes depending on the image that is analyzed.

After that, the user must introduce manually two treshhold values MIN/MAX for each color.

I would like to use inputdlg() to display as much prompt/inputs as needed according to the "colors" value.

Here a self made image of what I would like to have:

Thank you in advance.

Build an array of number needed -- but look at using a slider/spinner as perhaps more user friendly than typing...

xD dpb, “spinner” term made me chuckle.

Yes I was interpreting in another way xD. Nevertheless I admire the terms you use often.

OK...just in case you didn't realize there was one in the arsenal... :)

"I admire the terms you use often."

Indeed, I don't see any point in not having a little fun and humor along the way! Glad somebody sees similarly.

Something like this

num_colors = 4;
prompts = cell(1, num_colors*2);
prompts(1:2:end) = compose('Enter min value for color %d', 1:num_colors);
prompts(2:2:end) = compose('Enter max value for color %d', 1:num_colors);
out = inputdlg(prompts)

Hello again Ameer, it was really useful.

Here is what I've done to display a dialog for each one.

for i= 1:colors
    prompt2 = compose('Enter MIN value for color %d', i);
    content_coords(i,4) = eval(char(inputdlg(prompt2,dlgtitle1,dims1,definput)));
    prompt3 = compose('Enter MAX value for color %d', i);
    content_coords(i,5) = eval(char(inputdlg(prompt3,dlgtitle1,dims1,definput)));   
end

Thank you.
