disp() just displays the variable value in some default format. fprintf() gives you complete control over the format and how the printed output looks.

Please explain with example if easy for you. Especially i am confused regarding limitations of both commands. In which applications/scenarios one command should be used while in which applications should we use second command?

Try this:
myValue1 = exp(1);
myValue2 = pi;
disp('Here are the results of disp()');
format short g;
disp(myValue1)
disp(myValue2)
format long g;
disp(myValue1)
disp(myValue2)
fprintf('\nHere are the results for fprintf().\n');
fprintf(' The value for e is %f (with default number of decimal places).\n The value for pi (to 5 decimal places) is %.5f.\n', myValue1, myValue2);
to see, in the command window, the bare bones, basic stuff given by disp(), and the highly customized output that I told fprintf() to make:
Here are the results of disp()
2.7183
3.1416
2.71828182845905
3.14159265358979
Here are the results for fprintf().
The value for e is 2.718282 (with default number of decimal places).
The value for pi (to 5 decimal places) is 3.14159.
