CAT arguments dimensions are not consistent

Hi I am getting the following error :
*??? Error using ==> horzcat
CAT arguments dimensions are not consistent.*
But I am pretty sure that the dimensions are consistent. Please see below:
>> fn_trades = horzcat(trades.textdata(2:length(trades.textdata),1:2), trades.data(1:length(trades.data),1:2))
??? Error using ==> horzcat
CAT arguments dimensions are not consistent.
>> size(trades.textdata(2:length(trades.textdata),1:2))
ans =
1927 2
>> size(trades.data(1:length(trades.data),1:2))
ans =
1927 2
As you can see, the sizes of the two vectors are the same. So horizontal concatenation should work ??
Any ideas ?

Attach "trades" in a .mat file so that we can try to reproduce it.
OK, found the answer. The first argument produces two text columns, while the second gives numeric. So it doesn't want to cat.
This works (note the num2cell):
fn_trades = [trades.textdata(2:length(trades.textdata),1:2) num2cell(trades.data(1:length(trades.data),1:2))]
That wouldn't account for a dimension mismatch error. You can cat char with double, e.g.,
>> ['aa' 66,67]
ans =
aaBC
