 From your submitted references, list one and notify what he/she thinks about you.4 AnswersHi can you please post the coding challenge questions here..I am sorry. Only thing I could say is that the challenge was standard and had questions from Cracking the Coding book. Many questions were language based and some were proper algorithm questions.Hey, what did you mention about your salary expectation that put them off. I have one coming up and was wondering.Show More ResponsesDo not bother to expect a pay of around 80K if you are not coming from top colleges. I said I am looking for in the range of 80k.

 What is function handle?3 AnswersI don't know.A function handle is a MATLAB value that provides a means of calling a function indirectly. http://www.mathworks.com/help/techdoc/matlab_prog/f2-38133.htmlA function handle is a data type that stores an association to a function. For example, you can use a function handle to construct anonymous functions or specify call back functions. Also, you can use a function handle to pass a function to another function, or call local functions from outside the main function.
