I can calculate two error individually. but i can't calculate two error simultaneously. I found two result individually which is given in below. but i want to merge both error and need a single answer for following code, but i can't. Please help me

clc clear idealx=10; appx=9; error1=((abs(idealx-appx))/idealx)*100 idealy=30; appy=31; error2=((abs(idealy-appy))/idealy)*100

Mehedi, how about

 ideal = [idealx; idealy];
 app   = [appx; appy]; 
 error = ((abs(ideal-app))./ideal)*100

Simply put the variables into corresponding vectors.
