how to sum cell array of symbolics in matlab

To sum a cell array of symbolic values element-wise in MATLAB, you can use a combination of cellfun and symfun. The cellfun function applies a given function to each element of the cell array, while the symfun function creates an anonymous function from a symbolic expression.

Assuming A is the cell array of symbolic values and you want to sum the elements element-wise, you can use the following code:

main.m
A = {sym('x'), sym('2*y'), sym('3*z')}; % example cell array of symbolics
f = symfun(sym('sum(x)'), sym('x')); % anonymous function for summing elements
result = cellfun(f, A); % apply the anonymous function to each cell element

In this example, A is a cell array of three symbolic expressions. These expressions are then used to create an anonymous function f which sums its input. Finally, the cellfun function is used to apply the f function to each element of the A cell array, resulting in a new cell array result which contains the element-wise sum of the A cell array.
