In the above code, the cellfun() applied the function stored in myFunction to each element of the cell one by one and store the result in the variable output.
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 cellfun() Function in MATLAB Check this link for more information about the arrayfun(). clcĪs you can see from the output, the function cos(x) is applied to each element of the matrix, and the result is stored in the variable output. For example, let’s apply a defined function to each element of a matrix. In the above code, the arrayfun() applied the function stored in myFunction to each element of the array one by one and store the result in the variable output. If you have a function and want to apply it to each element of the array or matrix, 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 arrayfun() to apply the given function to each element of the array or matrix. Iterate Through a Matrix Using arrayfun() Function in MATLAB Note the sequence by which the elements are displayed on the command window, and this is the sequence of the linear indexing. And using a loop and linear indexing, we displayed each element one by one on the command window. In the above, we used the numel() function to get the total number of elements present in the given matrix. For example, let’s iterate through a matrix using linear indexing. 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. So if you count from the first column, the last element is present at the sixth index. In linear indexing, the elements are present in the matrix starting from the first column. In the above code, we access the last element of the matrix using both kinds of indexing. 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.
