So what happens is that disp (fprintf (.)) first prints the text as per fprintf without a. An in column order, and writes the data to a text file. The reason for the specific behaviour mentioned in the question is the call to FILEprintf fprintf with a storage variable: nbytes fprintf () returns the number of bytes that fprintf writes, using any of the input arguments in the preceding syntaxes. The accepted styles are those used for Matlab's syntax. CPRINTF then displays the text in the Command Window using the specified STYLE argument. Str = sprintf(formatSpec,A1.,An) formats the data in arrays A1., An according to formatSpec in column order, and returns the results to string str.įprintf(fileID,formatSpec,A1.,An) applies the formatSpec to all elements of arrays A1. (39) Syntax: count cprintf (style,format.) Description: CPRINTF processes the specified text using the exact same FORMAT arguments accepted by the built-in SPRINTF and FPRINTF functions. What the docs show me is that sprintf is exclusively used for string formatting, which you can use for adding text to a graph, setting up sequential file names etc, whilst fprintf writes to a text file. So what happens is that disp(fprintf(.)) first prints the text as per fprintf without a storage variable, but disp sees only the storage variable of fprintf, which is the number of bytes of your string, hence the output.Īs an addition, if you want to display strings, you need STRINGprintf: sprintf: disp(sprintf('Hi %i all of you',2)) Nbytes = fprintf(_) returns the number of bytes that fprintf writes, using any of the input arguments in the preceding syntaxes. The working of the sprint() is the same as fprintf() but the only difference is that when we use fprintf() is used to write the data into a text file and by. The reason for the specific behaviour mentioned in the question is the call to FILEprintf fprintf with a storage variable: Basically, sprintf() is a string variable and that is created in Matlab memory that means we can create the string variable by using the sprintf() instead of writing it into a text file.
