Answer to Question #99178 in MatLAB for lana majeed

Question

Fun with find. Write a function to return the index of the value that is nearest to a desired
value. The function declaration should be: ind=findNearest(x, desiredVal). x is a
vector or matrix of values, and desiredVal is the scalar value you want to find. Do not
assume that desiredVal exists in x, rather find the value that is closest to desiredVal. If
multiple values (entries) have the same distance from desiredVal, return all of their indices.
Test your function to make sure it works on a few vectors and matrices. Useful functions are
abs, min, and find. Hint: You may have some trouble using min when x is a matrix. To convert a
matrix Q into a vector you can do something like y=Q(:). Then, doing m=min(y) will give
you the minimum value in Q. To find where this minimum occurs in Q, do ind=find(Q==m);
