Given the number x, y must be the summation of all integers from 1 to 2^x.
For instance if x=2 then y must be 1+2+3+4=10.
Given the matrix A, return B in which all the rows that have one or more <http://www.mathworks.com/help/techdoc/ref/nan.html NaN...
Check if sorted.
Input x = [1 2 0]
Output y is 0
Given the matrix a, return the index r of the row with the most nonzero elements. Assume there will always be exactly one row th...
Given two lists of numbers, determine the weighted average.
[1 2 3] and [10 15 20]

Calculate the nth Fibonacci number.
Given n, return f where f = fib(n) and f(1) = 1, f(2) = 1, f(3) = 2, ...
Given an integer n, make an n-by-n matrix made up of alternating ones and zeros as shown below. The a(1,1) should be 1.
Triangle numbers are the sums of successive integers. So 6 is a triangle number because
6 = 1 + 2 + 3
which can be displa...
Given an input vector x, find all elements of x less than 0 or greater than 10 and replace them with NaN.
Regardless of input, output the string 'yes'.
Flip the outermost columns of matrix A, so that the first column becomes the last and the last column becomes the first. All oth...
Given the input n, return true if n is odd or false if n is even.
There will always be at least one prime in the matrix.
Input in = [ 8 3

Remove the nth column from input matrix A and return the resulting matrix in output B.
A = [1 2 3; 4 5 6];
Write a function which returns every other element of the vector passed in. That is, it returns the all odd-numbered elements, s...
Find the sum of all the numbers of the input vector x.
Input x = [1 2 3 5]

Input x ...
In MATLAB, you create a vector by enclosing the elements in square brackets like so:
x = [1 2 3 4]
Commas are optional, s...
Given a and b, return the sum a+b in c.
