MATLAB: Can I change this

MATLAB

I have array_X

array_X=[1,1,1,0,1,0,0,0,1,0]

i want to change to

like this.

ans =

'1110100010'

how to change this?

Best Answer

k = num2str(array_X) ; % convert to string 
k(k ==' ') = [] ;  % remove spaces

There will be more other elegant ways.

MATLAB: How to access a group of bits from a string

It's a little ambiguous, but how about just indexing or subtracting '0':

X = '0 0 0 0 0 0 1 1 1 0 0 1 1 1 1 1 0 0 0 0'
% Get rid of any spaces
X(X==' ') = []
% Extract the three substrings
x1 = X(1:6)
x2 = X(7:12)
x3 = X(13:end)
% Convert to a numerical data type.
doubleX = X - '0'

In the command window:

X =
0 0 0 0 0 0 1 1 1 0 0 1 1 1 1 1 0 0 0 0
X =
00000011100111110000
x1 =
000000
x2 =
111001
x3 =
11110000
doubleX =
     0     0     0     0     0     0     1     1     1     0     0     1     1     1     1     1     0     0     0     0

I don't see why cell arrays would be necessary unless I misunderstood something.

MATLAB: How to find run length consecutive ones and zeros and their occurrence times in a binary sequence in MATLAB

You can use the TEXTSCAN function by specifying delimiters and then use LENGTH function to find the length of each sequence. After that, you can compute the number of occurrences with HIST function as in the example below:

%Creating a binary sequence in a string with no spaces 
s = [1 1 0 0 0 0 0 1 1 1 1 0 1 1 0 1 1 0 1 1 1 0 1 0 1 0 1 0 0 1 1 1];
s = sprintf('%d',s);
%Reading the consequences of 1's from the string by using 0's as delimiters
t1=textscan(s,'%s','delimiter','1','multipleDelimsAsOne',1);
% Converting cell array of cell into a single cell array
d = t1{:};
% Computing the length of each run by going through the array and assigning
% it into 
for k = 1:length(d)
      data(k) = length(d{k});
end
% Using histogram function to compute the number of times for each length
[number_times run_length] = hist(data, [1:max(data)])

To do the same operation for finding run lengths and frequencies of "zeros" instead of "'ones", change the delimiter in the TEXTSCAN function to be '1' instead of '0'.
