I am having a column matrix say 7*1. Now, i need to assign '0' to negative elements and '1' to positive elements in the matrix. Thank you in advance.
For example:
A=[ 0.468505878281799
-1.90580778081907
-2.25397431420907
-3.46546394734966
0.488991442582022
-1.68349064240944
0.377334138950664]
Expected output:
B= [ 1; 0; 0; 0; 1; 0; 1]

Ran in:
A=[ 0.468505878281799
-1.90580778081907
-2.25397431420907
-3.46546394734966
0.488991442582022
-1.68349064240944
0.377334138950664];
B=A>0
B = 7×1 logical array
1 0 0 0 1 0 1
