Check if sorted.
Input x = [1 2 0]
Output y is 0

At one time or another, we all had to memorize boring times tables. 5 times 5 is 25. 5 times 6 is 30. 12 times 12 is way more th...
Flip the outermost columns of matrix A, so that the first column becomes the last and the last column becomes the first. All oth...
Remove the nth column from input matrix A and return the resulting matrix in output B.
A = [1 2 3; 4 5 6];
Given an input vector x, find all elements of x less than 0 or greater than 10 and replace them with NaN.
Find the sum of all the numbers of the input vector x.
Input x = [1 2 3 5]
Output y is 11
Input x ...
Given a positive, scalar integer n, create a (2^n)-by-n double-precision matrix containing the binary numbers from 0 through 2^n...
Write a function which returns every other element of the vector passed in. That is, it returns the all odd-numbered elements, s...
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 n, find the sum of the digits that make up 2^n.
Input n = 7
Output b = 11
since 2^7 = 128, and 1 + ...
Write a function posX=findPosition(x,y) where x is a vector and y is the number that you are searching for.
A Collatz sequence is the sequence where, for a given number n, the next number in the sequence is either n/2 if the number is e...
Try out this test problem first.
Given the variable x as your input, multiply it by two and put the result in y.
Given a and b, return the sum a+b in c.
Given the input n, return true if n is odd or false if n is even.
Find the mean of each consecutive pair of numbers in the input row vector. For example,
x=[1 2 3] ----> y = [1.5 2.5]
Triangle numbers are the sums of successive integers. So 6 is a triangle number because
6 = 1 + 2 + 3
which can be displa...
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.
Reverse the vector elements.
Input x = [1,2,3,4,5,6,7,8,9]
Output y = [9,8,7,6,5,4,3,2,1]
Output logical "true" if the input is the answer to life, the universe and everything. Otherwise, output logical "false".
Write a two-input, two-output function that swaps its two input arguments. For example:
[q,r] = swap(5,10)
returns q = ...
Regardless of input, output the string 'yes'.
Suppose you go from position 7 to 10 to 6 to 4. Then you have walked 9 units of distance, since 7 to 10 is 3 units, 10 to 6 is 4...

Return true if the elements of the input vector increase monotonically (i.e. each element is larger than the previous). Return f...
In MATLAB, you create a vector by enclosing the elements in square brackets like so:
x = [1 2 3 4]
Commas are optional, s...
