Matlab giving error for tall array assignment

Hello,

I need to use tall arrays because MATLAB is running out of memory due to the size of my V matrix ( there is a long checking and filling sequence using a random sequential adsoprtion algorithm) after the bit of code I am including here. How do I fix this error?

rng(69)
n = 10;
grid = 3;
% Coupon dimensions
Length = 76;
Width = 25;
mesh_size =1;
% Coupon dimensions
[X,Y] = meshgrid(-Length:mesh_size:Length, -Width:mesh_size:Width);
% Coupon dimensions
[X3,Y3,Z3] = meshgrid(-grid:mesh_size:grid, -grid:mesh_size:grid, 1:n);

Error using grid
Too many output arguments.

S = zeros(size(X));
smallV = zeros(size(X, 1), size(X, 2), n);
V = tall(V);
A = V;

Error using tensiletest

Argument 1 to SUBSASGN must be one of the following data types: logical.

The code doesn't define a variable named grid. It's getting confused with the function grid

Hello! I forgot to include it in the questions, the grid element is actually defined.

Now that the variable grid is defined, we have a new problem. The variable V is not defined.

rng(69)
n = 10;
grid = 3;
% Coupon dimensions
Length = 76;
Width = 25;
mesh_size =1;
% Coupon dimensions
[X,Y] = meshgrid(-Length:mesh_size:Length, -Width:mesh_size:Width);
% Coupon dimensions
[X3,Y3,Z3] = meshgrid(-grid:mesh_size:grid, -grid:mesh_size:grid, 1:n);
S = zeros(size(X));
smallV = zeros(size(X, 1), size(X, 2), n);
V = tall(V);

Unrecognized function or variable 'V'.

A = V;
