Copy Code Copy Command Read a file and search it for text of interest. First, read the file fileread.m into a character vector. Get filetext = fileread('fileread.m'); Then, define the text to search for. Get expr = '[^\n]*fileread[^\n]*'; Find and return all lines tha...
This default action can be changed by placing the STREAM in either control-data mode or control-discard mode with the I_SRDOPT ioctl() command. In control-data mode, read() converts any control part to data and passes it to the application before passing any data part originally present ...
