add value to cell array in matlab

To add value to a cell array in MATLAB, you can use the curly braces {} to access a specific cell and assign a value to it. Here is an example:

main.m
% create a cell array
myCellArray = {1, 'hello', [2 3 4]};

% add a value to the end of the cell array
myCellArray{end+1} = 'new value';

% print the updated cell array
disp(myCellArray);
188 chars
9 lines

In this example, we first create a cell array myCellArray that contains a numeric value, a string, and a vector. We then use the {} operator to add a new value (in this case, a string 'new value') to the end of the array by assigning it to myCellArray{end+1}. Finally, we use disp to print the updated cell array to the console.

Note that if you want to add a new row or column of cells to the array, you can use the cat function. For example:

main.m
% create a cell array of size 2x3
myCellArray = {1, 'hello', [2 3 4]; 'world', 5, 6};

% create a new row of cells to add
newRow = {'new', 'row', 'values'};

% add the new row to the bottom of the array
myCellArray = cat(1, myCellArray, newRow);

% print the updated cell array
disp(myCellArray);

In this example, we first create a cell array myCellArray of size 2x3 that contains a mix of numeric, string, and vector values. We then create a new row of cells newRow that we want to add to the bottom of the array. To do this, we use the cat function with the first argument 1 to concatenate myCellArray and newRow along the rows (i.e., on top of each other). The resulting cell array is then assigned back to myCellArray, which is printed to the console using disp.
