Matrix size is changed at each iteration.

Hi, My matrix size is changing at each iteration and the dimensions don't match as a result. I thought to produce a zero matrix of higher dimensions and replace the zeros with the current row matrix but I can't seem to do it. The code is as follows. Is there any other way I can handle this problem?

Any help would be really appreciated.

Thank you.

p2 = single(zeros(25));
preliminary_seed = [1 preliminary_seed];
        if counter_1 == 1
            p2(counter_1,:) = preliminary_seed;
            else
            seed1 = p2(counter_1-1,:);
            seed2 = preliminary_seed;
            if numel(seed2) > numel(seed1)
                seed1(end+1:numel(seed2))= 0;
            elseif numel(seed1) > numel(seed2)
                seed2(end+1:numel(seed1)) = 0;
            else
                seed2;
            end
            p2(counter_1,:) = seed2;
        end

Could you post the whole code (with your real data, or some sample data), it's hard to tell what's going on there without it

The code does not even run. What is preliminary_seed and counter_1?

[Kingshuk Islam]

Hi, thank you for your time. It is hard to provide the whole code as some of it requires excel data and I cannot provide it currently. But thank you again. Any suggestion on general solution of my problem?

[Walter Roberson]

The general solution starts with documentation of what the intended purpose of the code is and comments for each significant block of code.

Questions:

• Did you make this code yourself and thus know in some detail how it is intended to work?
• Do you use the debugging features "all the time"? If not, see Debug a MATLAB Program

Proposal:

• In the Editor group of the Toolstrip there is a button named Breakpoints. Activate "Stop on Errors"
• Start your program
• Inspect the values of variables in line which causes the error.
• Etc.
• Return here when you have specific questions.

This runs, but the result isn't useful

function    p2 = cssm()
p2 = single(zeros(25));
preliminary_seed = [1,randi(12,1,24)];

for counter_1 = 1 : length( preliminary_seed )
    if counter_1 == 1
        p2(counter_1,:) = preliminary_seed;
    else
        seed1 = p2(counter_1-1,:);
        seed2 = preliminary_seed;
        if numel(seed2) > numel(seed1)
            seed1(end+1:numel(seed2))= 0;
        elseif numel(seed1) > numel(seed2)
            seed2(end+1:numel(seed1)) = 0;
        else
            seed2;
        end
        p2(counter_1,:) = seed2;
    end
end
end

I since I don't know neither the start value of preliminary_seed nor the intent ...
