How to name by checking the entrys of a table?

Hi Guys, i I'm new in matlab so i need a little help to get started.

What i'm doning is to use the fullfact Method to create a table. There are 5 columns then and 216 rows. The number of factors depends - let me show you:

diameter=[ 10 15];                  % diameter in mm
density=[ 0 50 100];                % density in percent
orientation=[ 0, 45, 90];           % orientaion in degree
seam=[0,1];                         % 0 align, 1 random (can be adjusted to strings if really wanted)
layheight=[ 0.2 0.3 0.4];           % layheigth in mm
contournumbers=[1 2];                % numbers of contours

What i want to do is to get a logic naming of the single parts.

% Density: FG1, FG2
% Orientation: O0 O45 O90
% Seam: SO, SC
% Diamater: D15, D20 
% Layheight: LL, LM, LH
% contournumbers: C1, C2 

So a example of the part with all factor to be on 1 would be: FG1_O0_SO_D15_LL_C1

How can i like get a new table where matlab checks the entry of the columns in each row and depending on the entry get me out a new table with the naming?

Would be logic to get with "for" through all of the datas, but actually i can not figure out how to get me a string with a internal if function.

hope you guys can help me!

Thanks in advance!

I do not understand the question. "use the fullfact Method to create a table" is not clear. fullfact replies a matrix, doesn't it? Then how is the table created? "get a logic naming of the single parts" - what are "parts"?

The best help you will get is advice to avoid what you are trying to do:

"How can i like get a new table where matlab checks the entry of the columns in each row and depending on the entry get me out a new table with the naming?"

Ugh. Forcing meta-data into variable names is one way that some beginners force themselves into writing pointlessly slow, complex, buggy code that is hard to debug. Read this to know why:

"FG1_O0_SO_D15_LL_C1" seems to be an extremely ugly name for a variable or name of a table column. Here you hide important information in the name in a very cryptic fashion. It sounds like you want to create these variables dynamically, which is a very bad idea - see TUTORIAL: Eval .

Prefer to store the data in a clear way. E.g. a struct with the fields 'Density', 'Orientation', ... is much better than a magically encrypted keyword like 'FG1_O0_SO_D15_LL_C1'.

I'm not sure what "get me out a new table with the naming" means, but this condensed name is not useful as header or a table also, because it is confusing for a human reader and unnecessarily compact for the computer.

Thanks guys,

i figured out how to do it. Actually the naming was just a sample. i need this Funktion to read out the Matrix a couple more times. BBut it works now, so all good :)
