exit from the cycle

Hello! If I create a cycle, I need it, when the cycle was executed, it went to the next column and saved the number of digits until it was executed

for i = 1:length(A)
    if A(i,i)<A(i,i) % column and row number
       B{i}=A
    end
end

and I have two questions

1) how to end a cycle when conditions are fulfilled for the first time

2) how to work with rows and columns

1) how to end a cycle when conditions are fulfilled for the first time

Use break keyword to exit cycle as

for i = 1:length(A)
    % actually "A(i,i)<A(i,i)"it always fails
    if A(i,i)<threshold_value %comparing fake threshold_value % condition
       B{i}=A;
       break;    % to break cycle
    end
end

2) how to work with rows and columns

To work with rows and columns use to for loops as

for i = 1:size(A,1)     % for row access
    for j = 1:size(A,2)    % for column access
    if A(i,j) < threshold_value % condition
       B{i, j}=A;    % some opeartion
    end
end

Use break to exit loop

• 2) how to work with rows and columns

The question is unclear. You can use 2 for loops

for i = 1:size(A,1)        % rows
    for j = 1:size(A,2)    % columns
        % if ...
    end
end
