C/C++: Lots of program on classes to determine output, whether it will compile? Focus: Operator overloading, Virtual functions, Constructors: A sample is given below:(determine whether it will compile) class xyz { \\somethings here }; int main() { xyz s1=new xyz(100); xyz s2=s1; s2.function(); delete s1; } Very easy for comp. sci. ppl

MATLAB: 1. a=[1 2 3 4]; you have to scale each element by following scaling factor: scale=[10 20 30 40]...how would you do it? Ans: a.*scale; 2. a=[1 2 3; 4 5 6; 7 8 9] a.*scale will work? No...matlab will give error 3. can you define a function called filter.m? Ans: No, coz filter() is a matlab pre-existing fxn. But what if filter is in the current folder? You still should not do that, coz filter() will always resolve to MATLAB's fxn. 4. logical indexing question It should be pretty easy

MATH: 1. given velocity, v(t) find acceleration a(t) and displacement d(t): SImple integral and derivative 2. Question on rank of a matrix and was given a matrix and was asked rank 3. whats characteristic eqn. of a matrix? Was given a matrix and was supposed to find the equation 4. When is a matrix convertible? A matrix was given 5. given v1=i-j v2=k; find a vector perpendicular to v1 and v2... use cross product Should be simple...
