If you have a function and want to apply it to each element of a given cell, one way to do that is to iterate through each element as described above and apply the function on each element, but there is another easy method in which you can use the cellfun() to apply the given function to each element of the cell. Iterate Through a Matrix Using Linear Indexing in MATLAB In a matrix, there are two kinds of indexing; one is the row and column indexing in which we have to give the row and column number to access an element present in the matrix, second is the linear indexing in which we can access an element using only its linear index. Matlab. sites are not optimized for visits from your location.
