MATLAB: How can i concatenate array of 3 to form single matrix

3d array; array;

i am very new to matlab, so sorry if i sounded stupid
i just need to get an output of 3 array from my looping and form one single 3d matrix
for example
100 array x 10 array x 12 array and store it as 3d matrix
so that the size will be : 100 x 10 x 12
any idea?
and thank you in advanced

A bold guess:
x = 1:100;
y = 1:10;
z = 1:12;
Result = reshape(x, [], 1, 1) + reshape(y, 1, [], 1) + reshape(z, 1, 1, []);
Here I assumes, that you want to combine the values by an addition.
This runs in R2016b. The reshape commands are formulated equivalently for demonstration purposes only: In the first you can omit the trailing 1, the second is not needed because y has the wanted shape already.
For earlier version, the addition of arrays with different shapes required bsxfun:
Result = bsxfun(@plus, reshape(x, [], 1, 1), ...
                       bsxfun(@plus, reshape(y, 1, [], 1), reshape(z, 1, 1, [])));
