There are 2 columns
1 - (MH12GJ8059, CH15HJ5456, MH14KS6516, KA45HS1654)
2 - (XXYYXX, GSGGYY, YSHHSG, HHSHHH)
now is there a way in Matlab so that it asks for user inputs and displays the respective data next to it.
eg, input = MH12GJ8059 (from user)
output = XXYYXX

doc ismember
should do the job, using the 2nd output argument to give you the index to apply to the other array/column/whatever.

Hi,
You may use the following code. Last 3 lines may be put inside a loop for repetition.
x = string(['MH12GJ8059'; 'CH15HJ5456'; 'MH14KS6516'; 'KA45HS1654']);
y = string(['XXYYXX'; 'GSGGYY'; 'YSHHSG'; 'HHSHHH']);
inp = input('Enter a string');
[val,ind] = ismember(string(inp),x);
disp(y(ind));
As Adam has mentioned, you can make use of the MATLAB documentation to gain more insight into the functions.

Yeah. No need of string command there.
x = {'MH12GJ8059'; 'CH15HJ5456'; 'MH14KS6516'; 'KA45HS1654'};
y = {'XXYYXX'; 'GSGGYY'; 'YSHHSG'; 'HHSHHH'};
inp = input('Enter a string');
[val,ind] = ismember(string(inp),x);
disp(y{ind});
