MATLAB: How i count the values.

MATLABmatrix

suppose, a=[1,2,3,4,5,6,7,8], the size of this matrix 1 rows and 8 columns and total values are 8, how can we count these total values on MATLAB. the result should be show like as 8 means if a has total values 1000 then the result should be 1000.

Best Answer

What exactly do you mean by count? Do you mean the sum (total) of all elements, or the number of elements? Do you mean a count of the number of elements? Like
numberOfColumns = size(a, 2);
numberOfColumns = length(a);
numberOfColumns = numel(a);
All of the above will give numberOfColumns = 8 for an 8 element row vector, and numberOfColumns = 1000 for a 1000 element row vector.
