I have two different variables. First variable is comprised of 104x1 cells and second variable is comprised of 160x240 cells. I have to develop a dictionary that contains both of these variables. How should I do it? I have move through different tutorials of building dictionary, but I cannot understand.

Kindly guide me How do I do it?

Basically I am working on image processing, processing each frame gives me two variable as mentioned above. I have two add these variables in dictionary in such a way that these variable are only stored in it without any key values. So I dont want any dictionary-like data structure. I hope so I cleared my point.

You are very unclear about your problem.

I think you are simply trying to combine these two variables into one structure, in which case either use a cell array, or a strcture.

a = ones(104, 1);
b = ones(160, 240);
c = {a, b}; % - cell array
d = struct('a', a, 'b', b) % - structure

uniquevars = unique([First{:}; Second{:}]);

This will just be a list of the all of the values that occur, without there being any dictionary data structure involved.

This command pass me an error as:

Dimensions of matrices being concatenated are not consistent

As my first variable has size 104x1 cells while other is 160x240 cells.

I have to build up a dictionary where I can store these two variables. If you have anyother solution, do share.

Thanks

First_vec = cellfun(@(v) v(:), First, 'uniform', 0);
Second_vec = cellfun(@(v) v(:), Second, 'uniform', 0);
uniquevars = unique([First_vec{:}; Second_vec{:}]);

I have to build up a dictionary where I can store these two variables.

You specifically told us earlier "So I dont want any dictionary-like data structure", and "in such a way that these variable are only stored in it without any key values", so we are led to believe that you simulateneously want a dictionary and specifically do not want a dictionary.

Suppose that all of the cells are examined and the unique values over all of the cells are found, and suppose there are 583 of them. Now consider the 309'th of those unique values. Do you need to be able to pass in that 309'th value and use it to retrieve some associated data? Do you need to be able to pass in (something else) and use it to retrieve that 309'th value? Are the values being extracted to be used as the keys or as the data associated with the keys? Or is the data just implied, such as building a spell checking system in which at any point want you want to know is "Is this a known word?" (is the word present in the list of known words, or not present) ?
