Concatenating a double array and two cell arrays

Hi there,

I'm trying to add to arrays (a & b) to my data set, which should be very simple, but I keep running into problems.

The working pieces:

 >> whos a
    Name        Size            Bytes  Class    Attributes

    a         759x1             89562  cell               

>> whos b
  Name        Size            Bytes  Class    Attributes

    b         759x1             94116  cell               

>> whos site_Cflux
  Name              Size            Bytes  Class     Attributes

    site_Cflux      759x3             18216  double

Example of my code:

sitedata=horzcat(a, b, site_Cflux)

Which should work (they all have the same number of rows), but I get this message:

Error using horzcat Dimensions of matrices being concatenated are not consistent.

Any ideas? Is this a cell array/double array issue? I thought they were compatible.

Thanks a million.

does this work

sitedata=horzcat(a, b, num2cell(site_Cflux))

Perfect, thanks a bunch

No problem, please accept my answer

Absolutely! One quick question, do you think that there is a way to do this without turning my number matrix into a cell matrix? I can't run some of my functions on the data now (example: rem).

Nope. If you want to have the entries from site_Cflux be placed against the corresponding row entries of "a" and "b", then you need to break up the numeric array to become cell entries.

You can extract from the cell and convert back to numeric arrays if you need to.

And naturally if "a" and "b" contain numeric values, some number of entries for each row, then you could convert the whole thing to a single numeric array:

horzcat(cell2mat(a), cell2mat(b), site_Cflux)

I end up getting error messages like this:

Undefined function 'rem' for input arguments of type 'cell'.
