logical operators with while loop

    %Find the smallest even integer that is 
    % divisible by 13 and whose 
    % square root is greater than 86 
    
    clc;
    clear;
    x=15;
    a=rem(x,26);
    b=sqrt(x);
    
    while a==0 && b>86
    if a==0 && b>86
        fprintf('The required number is %d\n',x);
         break
    else 
        x=x+1;
    end
       
    end

At the risk of doing someones homework :P

clc;
clear;
x = 0; % or start at x = 86^2;
while true
    a = rem(x,13);
    b = sqrt(x);
    if a==0 && b>86
        fprintf('The required number is %d\n',x);
        break;
    else
        x=x+2;
    end
end

thanks man.Now it is working.

Answer 2

[David Hill]

a=7397;
while ~(mod(a,13)==0&&mod(a,2)==0)
    a=a+1;
end

Answer 3

[KSSV]

x = 2 ; 
while ~(mod(x,13) == 0 && sqrt(x)>=86)
  x = x+2 ;
end
fprintf('The required number is %d\n',x);

The required number is 7410
