Problem 1 Write a M-file script that creates a row vector that has 100 elements with dimensions of (1 x 100) and name the vector a. The first 25 elements have of value 1, the next 25 elements have value of zero, the next 25 elements have value of 2, the next 25 elements have value of -1. Concatenate the four sub arrays into an array named a Include the size function to determine the dimensions of the array progmanatically. Assign the variable vector_size to the size function as the output. Hint: vector_size must have two elements and dimensions of (1 x 2). This must be constructed programmatically i.e. you cannot type vector-size = [anumber anothernumber; Next using indexing include code to assign the variable a89 to equal the value of the 89th element of a You must include comments describing your code!

Expert Answer

a = zeros(1,100);
[r,c] = size(a);
for i=1:r
for j=1:c
if j>=1 && j<=25
a(i,j) = 1;
elseif j>=26 && j<=50
a(i,j) = 0;
elseif j>=51 && j<=75
a(i,j) = 2;
else
a(i,j) = -1;
end

end
end
a
vector_size = size(a)
