Latest activity Commented on by Yusuf Dhoda on 24 Oct 2019
I have a 32768x2 double array that contains a 2 bit binary signal. I want to convert this 2 bit binary signal to a value between 1 and -1. For example:
01 ----- 1
00 ----- 0.5
10 ----- -0.5
11 ----- -1
I want to store the results in a 32768x1 array
Thank you

Try the below code. It should work fine.
clear all
a=your_array; %Assign your array to the vaiable 'a'
L=size(a,1);%Get number of rows in a
d=bi2de(a,'left-msb'); %Convert binary vectors to decimal numbers with 1st column as MSB. use, d=bi2de(a) if you want 1st column as LSB
for i=1:L
switch d(i)
case 1
case 0
case 2
case 3
b=b'; % Final answer
