Cell arrays and matrices have numerous syntactic and semantic differences, even though both are N-dimensional data structures. In order to iterate a matrix using row and column indexing, you require two loops, but in the case of linear indexing, you only require one loop. There is no shortest path between any pair of vertices , which form part of a negative cycle, because path-lengths from to can be arbitrarily small (negative).

Not as fast as vectorized methods if you want to check all the points, but if you don't need to evaluate most of them it can be quite a time saver. of arbitrary dimension, you can use arrayfun to apply my_func to each element: If A is a cell array of arbitrary dimension, you can use cellfun to apply my_func to each cell: The function my_func has to accept A as an input. Thank you all! As you stated that Q and G are zero matrices generated for memoty allocation if so, and you want to to fill out the values of Q respectively with G. Then the solution code is this one: " the latter is an array of equal size and composed of logical values. https://www.mathworks.com/matlabcentral/answers/416833-for-loop-moving-through-array, https://www.mathworks.com/matlabcentral/answers/416833-for-loop-moving-through-array#comment_604810, https://www.mathworks.com/matlabcentral/answers/416833-for-loop-moving-through-array#answer_334698, https://www.mathworks.com/matlabcentral/answers/416833-for-loop-moving-through-array#answer_334695.
