Array dimensions must agree vertcat

I've been trying to concatenate two cell arrays (both of which are 1x157) and I can use vertcat to do so in using the input/command line but I get an "Dimensions of matrices being concatenated are not consistent.:" error when I do so in a function. Is there anything I can do or will I have to perform the concatenation manually every time I need to?

My guess is both arrays are not 1x157. Is one of them 157x1? Because this works fine:

x = rand(1,157);
y = rand(1,157);
z = vertcat(x,y);

However,

x = rand(1,157);
y = rand(157,1);
z = vertcat(x,y);
Error using vertcat
Dimensions of matrices being concatenated are not consistent.

When I output the two cell arrays I'm trying to concatenate as workspace variables they display as 1x157 cells. I'll check again though. Edit: They're the same size but it's still not working. One of them is an array of constants so I just ended up copying the data directly into the function and made a new variable for it.

Are you sure the constants are cells? Because

x = rand(1,157);
y = cell([1 157]);
z = vertcat(x,y);
Error using vertcat
Dimensions of matrices being concatenated are not consistent.

But if you convert x to a cell array it works:

x = rand(1,157);
y = cell([1 157]);
z = vertcat(num2cell(x),y);
