Is there a way to re-initialize an existing cell / array without specifying the dimensions of said cell / array?
Ie.
tempArr1(7,5) = zeros % First instance of use
tempArr1 = some function or command % Second instance of use returning the tempArr1 (7,5) of zeros?

To set all the values of array x to 0:
x(:) = 0;

Implicitly invoke the creation of a cell/array using the size of the object you want:
A=cell(4,5,6);
B=cell(size(A))
A=zeros(3,4,5);
B=zeros(size(A))
Is that what you need?

tempArray(:) = 0;
Or
tempArray = zeros(sizeof(tempArray), class(tempArray) ) ;
Or
tempArray = 0 * tempArray ;
For cells...
tempArray = cellfun(@(C) 0*C,tempArray, 'uniform', 0)
