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 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.
Given an input vector x, find all elements of x less than 0 or greater than 10 and replace them with NaN.
Triangle numbers are the sums of successive integers. So 6 is a triangle number because
6 = 1 + 2 + 3
which can be displa...
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...
Given the input n, return true if n is odd or false if n is even.
Given a and b, return the sum a+b in c.
In MATLAB, you create a vector by enclosing the elements in square brackets like so:
x = [1 2 3 4]
Commas are optional, s...
Find the sum of all the numbers of the input vector x.
Input x = [1 2 3 5]
Output y is 11
Input x ...
