Hi,

I have a question regarding implementing a for and if loop with cell arrays.

I have a matrix A{1x24 cell} Each cell contains ages of people, but each cell has a different length (i.e. A{1} is 2362x1, while A{2} is 2344x1, etc.).

Now I want to apply an if loop that for each value in A which is >=1, that specific value will be subtracted by 1.

Can anyone help me with this?

在 MATLAB Online 中打开

Some fake data to try, and the loop:

A{3} = 2:5;
A{2} = -3:4;
A{1} = -2:2;
for k = 1:numel(A)
    idx = A{k}>=1;
    A{k}(idx) = A{k}(idx) - 1;
end

Please ask this in a new question, giving both input and output example data for us to try. Currently it is not clear what "B containing matrices" means, ditto "The second column defines their salary", etc. Is the salary "defined" as a value, a code, a category, a name, an index, or something else?

Without example data arrays we cannot try our code and we cannot test our code.
