and memory footprint. The content of each element is also completely different. Therefore, the elements of the cell array are called cell (cell ).Applicable situation:Suppose you need to save 4 sets of information in MATLAB. They are:We use MATLAB to store them in a 2×2 cell array, ...
I have an array of single column data, array length of about ~8000 members. I want to print some data interval from array, so id array is named 'data', I use a single line data(6500:end) and this outputs a list of elements starting of element#6500 to the end of array. How I ...
The cell array is a special data type of MATLAB. The cell array is regarded as an all-encompassing general matrix, or generalized matrix. The elements that make up a cell array are constants or constants of any data type. Each element also has a different size and memory footprint. The ...
