Specify one dimension as variable size in Matlab Coder

Hi!

I wish to graphically (in the matlab coder window) specify one dimension of an input as variable size and one dimension as fixed size. How do I achieve this?

Hi,

I guess you mean the MATLAB Coder project settings? When you specify the input variable, use a ":" to specify a variable dimension, e.g.,

:10 x 1

makes the number of rows variable (between 1,...,10) and the number of columns fixed. Use

:inf x 1

if you don't want to have an upper limit. Depending on the code you will need to use "dynamic memory" (on the memory tab) ...

Hi,

Although i did not understand your question very well but this is i think is your question :-

If you want to create a variable 'a' of dimension x by 23 and you want x to be given by a user , then you can do that by coding very easily, Just input x , and create a as follows for example -

a = zeros(x,23);

As far as doing it graphically is concerned, which i think is ur question, then well design a GUI and from there take the input x. After that you can write the corresponding code as the same.

Hope it helps
