Dear Experiences

i have a table that look like the following:

Table:

Name      RC     BV     CC    RQ     CY ..... TY 
A1        1      0      1     0      1        0
A2        1      0      0     0      0        0
A3        0      1      1     0      1        0
A4        0      0      0     0      0        1

then for the given query word such as ( A1 ) then the result perhaps store in cell array like:

Result ={ RC , CC , CY ,...} where the values of A1 in the corresponding columns header are 1.

i would thanks any one can give me help.

You could also make Name the row names, i which case Walter's answer looks like

YourTable.Properties.VariableNames( logical(YourTable{'A1',:}) )

thanks, your code its retrieve the values of first row A1, while my request perhaps retrieve the columns headers, so according to my example in the above table the result of A1 ={RC, CC, CY} because the values of A1 row are 1 in these columns headers.
