i need help with this>?

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

ans = [15    30     5];

How to produce answer with specified data is replaced and original data which falls out of if condition is unchanged...

[Chandrasekhar]

A(A>5) = 5.
elements of A which are greater than 5 are replaced with 5
Is this what you are looking for?

Yeah your edited function is working good. Thanks. Just wanted to improve my logic
