Storing variables in a for loop within another

I have the code below, and I want to store the variable "vetor_momentoj" returned from the for loop in terms of the indexes i and j. In other words, in each interaction i, I will have j (10) values of the variable "vetor_momentoj". Similarly, I want to store the variable "jvals". In each interaction i it's assuming a vector of values as declared with linspace. Can anyone help me, please?

it = 10000;
jvals = zeros(it,1);
vetor_momentoj = zeros(it,1);
for i = 1:it
    jvals(i) = linspace(0, 0.03, 10);
    for j = 1:numel(jvals)
        curvatura = jvals(j);
        funj = @dissertacao_curvatura_funcao;
        x0j = 1;
        xj = fzero(funj,x0j);
        vetor_momentoj(j) = momentoj;
    end
end

"store the variable "vetor_momentoj" [...] in terms of the indexes i and j."

Something like this? I replaced the calculation of momentoj by rand to be able to run the script.

There is no reason to have the statement jvals = linspace(0, 0.03, 10); inside the loop. The value of jvals doesn't change.

%%
it = 10000;
jvals = linspace(0, 0.03, 10);
vetor_momentoj = nan( numel(jvals), it );
for i = 1:it
    for j = 1:numel(jvals)
        curvatura = jvals(j);
%       funj = @dissertacao_curvatura_funcao;
        x0j = 1;
%       xj = fzero(funj,x0j);
        vetor_momentoj(j,i) = rand; % momentoj;
    end
end
whos vetor_momentoj

  Name                 Size                Bytes  Class     Attributes

  vetor_momentoj      10x10000            800000  double              

"store the variable "jvals"." I don't see why. The statement jvals(i) = linspace(0, 0.03, 10); throws an error. repmat( linspace(0,0.03,10), .... ) outside the script, isn't that good enough?

Thank you! But the variable jvals has to be inside the loop. The value 0.03 I put here is hypotetical, in the real code it's a value that depends on the index i. So how should I proceed?

[Stephen23]

it = 10000;
nc = 10;
jvals = nan(it,nc);
vetor_momentoj = zeros(it,1);
for ii = 1:it
    V = linspace(0, 0.03, nc);
    for jj = 1:numel(V)
        curvatura = V; % this variable is unused
        funj = @dissertacao_curvatura_funcao; % why redefine this on every iteration?
        x0j = 1; % why redefine this on every iteration?
        xj = fzero(funj,x0j);
        vetor_momentoj(jj) = momentoj; % where is MOMENTOJ defined?
    end
    jvals(ii,:) = V;
end

Did you find a solution?

Yes, thank you!!
