Hi all
i need help with my assignment
a)using for loop
b)using array masking
Write a function that accepts an array A in its arguments and returns the array B that is computed from array A such that: a. Elements in A less than or equal to -2 are replaced by 30. b. Elements in A greater than -2 and less than 5 are replaced by 15. c. Elements greater than 5 are replaced by 5. Test your function with A=[2,5,10;-8,-1,11;43,6,-2]

for ex:
A=[2,5,10;-8,-1,11;43,6,-2];
>> A(A < -2) = 30

A=[2,5,10;-8,-1,11;43,6,-2];
function B = ReplaceFunction(A)
[m,n] = size(A);
for i = 1:m
for j = 1:n
if(A(i,j)<=-2)
B(i,j) = 30;
else if(A(i,j)>-2 && A(i,j)<=5)
B(i,j) = 15;
else
B(i,j) = 5;
end
end
end
end
