MATLAB: How to define binary matrix in matlab

binarymatrix

let's suppose that i have this matrix

A=[0001

0010;

0011;

0100;

0101]

how can i define it to matlab so that it will be reconized as binary matrix and not double ?

If you mean that you type in the A matrix exactly as above, but want to reinterpret the decimal digits as binary digits, then maybe something like this:

>> A=[0001
0010;
0011;
0100;
0101]
A =
     1
    10
    11
   100
   101
>> bin = reshape(sprintf('%04d',A),4,[])'
bin =
0001
0010
0011
0100
0101

If you wanted that as a logical matrix instead of a char matrix, then

bin = (bin == '1')

For the First part of the question please refer to link here (@Walter Roberson's answer)

Second part, this is broad way to express-

Here I trying one example, please look

>> a=randi(5,5)
a =
     1     5     2     5     4
     5     5     4     4     4
     3     3     2     2     5
     5     2     4     4     5
     4     1     1     2     2
>> binary=(a<3)
binary =
     1     0     1     0     0
     0     0     0     0     0
     0     0     1     1     0
     0     1     0     0     0
     0     1     1     1     1

Here this is logical expression

If you are talking to decimal to binary, as processor do the computaion in binary values only, all decimal elements convert to binary as general. I hope you know the procedure.

MATLAB: How to separate signals with diffrent frequencies

Add the following lines of code at the bottom of your code (after y=x+randn(size(x)).*sigma;):

ffty = fft(y);
ffty = abs(ffty(1:ceil(length(y)/2)));
ffty(ffty<100)=0;
[~,locs] = findpeaks(ffty);
freqs = (locs-1)/t(end)
signal_1 = sin(2*pi*t*freqs(1))+sin(2*pi*t*freqs(2))+sin(2*pi*t*freqs(3)); % 3-10
signal_2 = sin(2*pi*t*freqs(6))+sin(2*pi*t*freqs(7)); % 50-100
subplot(211), plot(t,signal_1)
subplot(212), plot(t,signal_2)
