Create a script that will determine if number of a matrix are positive, zero or negative. The program will create an output matrix with -1, 0 and 1 that replaces negative, zero and positive numbers, You must use a nested for loop and conditional statements 1. nesptetivc) Mat [0 4-3;-102] Output [01-1;-10 1] 2. Write a for loop that will print the elements from variable sentence Tormat, regardless of the length of the vector. For example, if this is the vector >>vec [ 5.5 11 3.45] This would be the result: Element 1 is 5.50 Element 2 is 11.00 Element 3 is 3.45
