Iam having 2 6*1 matrix. Now i need to group elements in matrix A based on same value. then i need to choose corresponding elements from matrix B.

For example

A = [0.367;0.264;0.264;0.2345;0.2345;0.367]

B = [01111;00111;10011;10010;10000;01110]

expected output :

group 1 : 0.367

01111,01110

group 2 : 0.264

00111,10011

group 3 : 0.2345

10010,10000

Numeric data types do not store leading zeros, so what is this array really?:

B = [01111;00111;10011;10010;10000;01110]

Is it in fact a character array or a string array or a categorical array or something else?

OP could be trying to store binary representation of numbers as numeric data.

G=findgroups(A(:));
splitapply(@(x){x}, B(:),G)

Thank you and your code works as per my requirement
