Accelerating the pace of engineering and science. Not the answer you're looking for? my question is when converting from dec to bin, how can i obtain the result in a matrix and not a char array, so that matlab reconize that the elements of this matrix are binary and not double, I assume by binary you really mean logical. As Bill the Lizard wrote you can use fread to load the data into a vector. Hexadecimal literals start with a 0x or 0X prefix, while binary literals start with a 0b or 0B prefix. Create and open a new file titled Untitled.m in the MATLAB Editor (or default editor). Languages/tools like C, C++, Matlab, IDL create 'flat' files.

This is a binary version of the AEFA scheme to improve the performance of the original AEFA scheme in discrete space. Description fid = fopen(filename) (On PCs, fopenopens files for binary read access.) writing each value. It is convenient to start with binary representation, but the number is stored as an integer. When you finish writing, close the file by calling fclose (fileID). When you are reading or writing binary, you have to pay attention to whether the file stores the values "down the columns" (the order that values are stored in memory in Matlab) or "across the rows" (the order humans tend to read in.).
