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 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.
input -> matrix (n*m) with at least one element equal to NaN;
output -> matrix(p*m), the same matrix where we deleted the enti...
If x=[0,3,4,2,1] then y=[4,3,2,1,0]
Return two random integers between 1 and 6, inclusive, to simulate rolling 2 dice.
If the input string s is a word like 'hello', then the output word product p is a number based on the correspondence a=1, b=2, ....
Given two lists of numbers, determine the weighted average.
[1 2 3] and [10 15 20]
should result in
Flip the outermost columns of matrix A, so that the first column becomes the last and the last column becomes the first. All oth...
Return true if the elements of the input vector increase monotonically (i.e. each element is larger than the previous). Return f...
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.
Regardless of input, output the string 'yes'.
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 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.
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 ...
