Concatenate str and int and store it as a vector

Hello,

I have two arrays which I would like to concatenate with a string and save it as vector for the following data.

A= [761,2,45,65,900]

B=[56,96,368,879,56]

string = sample

I would like to concatenate the above vectors A and B with the string in the following format [sample_761_56, sample_2_96, sample_45_368, sample_65_879, sample_900_56]

A = [761,2,45,65,900];
B = [56,96,368,879,56];
s = 'sample';
sprintfc([s, '_%d_%d'], [A; B].')

ans = 5×1 cell array
    {'sample_761_56'}
    {'sample_2_96'  }
    {'sample_45_368'}
    {'sample_65_879'}
    {'sample_900_56'}

% Or:
compose('sample_%d_%d', A', B')

ans = 5×1 cell array
    {'sample_761_56'}
    {'sample_2_96'  }
    {'sample_45_368'}
    {'sample_65_879'}
    {'sample_900_56'}

Thanks, the first option works. Compose function doesnt work for me.

S = "string";
S + "_" + A + "_" + B
