Re: length on a matrix

[James Sherman Jr.]

Hi,

I think copying and pasting the actual input and/or script you use might clarify the issue here.  I can't figure out what could be wrong but for example if you typed
length(test);
into the script, nothing would be output since you're suppressing the output to the screen and not assigning it to anything.  Furthermore,
size(test)
should have returned [8 x] where x is the number of columns in test1 (or test2) and not just 8.

I'm just a bit confused.

Hello,
simple question:
I did a matrix in this way:
test = [ test1(1:4, :); test2(1:4, :); ];

and after I like to know the number of the rows:

length(test);

but it returns '2'.
in fact, I use
size(test)
the number correct '8' is returned.

Could anybody tell me why length doens't work?
thanks,
