Find the greater number in a matrix

I am having 2 4*1 column matrix. one consists of 2-bit binary numbers & other matrix consists of decimal numbers. Now i need to find out the values which are greater than or equal to 0.22 in matrix B and store it in matrix C. again i need to compare resulant position values in matrix c with matrix b position and i need to pick the coressponding element in that position in matrix A. Thank you in advance.

Example:

A = [01 ; 10 ; 11 ; 00 ]

B = [0.234 ; 0.148 ; 0.226 ; 0.118]

Expected output :

C = [0.234 ; 0.226]

D = [01 ; 11]

This is a simple case of logical indexing.

A=[01 ; 10 ; 11 ; 00];
B=[0.234 ; 0.148 ; 0.226 ; 0.118];

Z=B>=0.22;
C=B(Z)

C = 2×1

0.2340 0.2260

D=A(Z)

D = 2×1

1 11
