MATLAB: Make header from numeric array

column header

Hi,

I have a numeric array and want to concatenate each element with a string. As I will use the new array as a header, it needs to end up as a cell array.

i am trying:

wl_arr = 400:1.85:2400;
hdr = strcat('L_conv_', num2cell(wl_arr));

but get this:

I also tried:

wl_arr_str = num2str(wl_arr);
rad_conv_hdr1 = strcat('L_conv_', wl_arr_str);

Best Answer

hdr = arrayfun(@(x) sprintf('L_conv_%f', x), wl_arr, 'unif', 0)

Use array2table instead of table (the wrong function, unless you really want the array in one variable).
Get rid of all of that cell2mat and strcat and str2mat confusion (what are you concatenating? Nothing).

all_sorted = [2;3;5];
result_matrix = randi(5,7)
result_matrix = 7×7
     5     1     1     1     1     2     2
     2     2     4     1     4     5     1
     5     5     2     4     5     3     3
     2     1     5     4     4     2     4
     3     3     2     5     1     4     5

nr = size(all_sorted,1);
C1 = arrayfun(@(x) sprintf('type%d', x), 1:nr, 'UniformOutput', false)
C1 = 1x3 cell array
    {'type1'}    {'type2'}    {'type3'}
C2 = arrayfun(@(x) sprintf('binary%d', x), 1:nr, 'UniformOutput', false)
C2 = 1x3 cell array
    {'binary1'}    {'binary2'}    {'binary3'}
VN = [C1,C2,{'result'}];
T = array2table(result_matrix, 'VariableNames',VN)
T = 7x7 table
    type1    type2    type3    binary1    binary2    binary3    result
