4 visualizzazioni (ultimi 30 giorni)
Hi everyone, i have a file of binary data(i.e. 0 and 1) only as , 128rows and 128 columns. all i want is my for loop to take one row or column at time and assign its value to key_out variable, and in next iteration it moves to 2nd row or column. Right now i have this code given below, but its not working fine, i will be very glad if someone can help me.
filename = 'binary.xlsx';
key_out=sprintf('%g', key_out);
key_out= reshape(key_out, [],128);
for j=1:128
my_out= masterkey (key_out);
%two more functions will be executed here, for each 128 bits of j

You need to specify row and column indices. Try this
for j=1:128
my_out= key_out(:,j); % extracts the jth column

You can do the same without Loop also (Using Cell Array)
  • Saving all Rows as key blocks
  • Or Saving all Cloumns data as key blocks
Later you call any data from cell array using key_blocks{row/column number}
