', 's') nxyzfile fopen(nxyzfilename, 'r') nxyz textscan(nxyzfile, '5d5d10.4f8.1f10.4f8.1f10.4f8.1f') fclose(nxyzfile) with the 'd' (stand for decimal. 1 The trick to this is to use a format item Theme Copy '' '''' for each place you want one of those quoted strings. Syntax: C textscan(fid, format) The function. MATLAB's textscan function is best suited for this operation.
#Matlab textscan format string code#
As the answer said, the right code is: nxyzfilename input(' Select the file. numerical data and a string of characters. Obviously, this means you'd have to know exactly how many digits there are in both numbers. Error using > textscan Badly formed format string. You'll see that the first string has its leading whitespace removed (and therefore has 3 characters "too many"), but for some reason, the last string keeps its trailing whitespace. This function is similar to textread, however it also allows you to read the.
#Matlab textscan format string how to#
I think this, because if you change yuor format string from '%9f%9f' For a string, it indicates how many characters were read. This example shows how to read an arbitrary format text file with textscan. I suspect textscan first trims leading white space, and then parses the format string. Is there any way I can read this string correctly using textscan or another built-in (for performance reasons) MATLAB function? My current workaround is to add commas between the fields and use commas as a delimiter in textscan, but that's slow and not a nice solution. ) where fid is the file id of a file that has already been opened with fopen, format is a string containing. Surprisingly, if we add a minus, we don't get an error, but a wrong result: dat = textscan(' -9574865.0E+10 ','%9f %9f','Delimiter','','CollectOutput',true,'ReturnOnError',false) a textscan(fid, 'format', N, param, value.
Trouble reading floating point number from file (row 1u, field 2u) => E+10 The following error is returned: Error using textscan The problem can be replicated like this: dat = textscan(' 9574865.0E+10 ','%9f %9f','Delimiter','','CollectOutput',true,'ReturnOnError',false) Eitan T at 13:32 2 You will get better help with this if you add a few lines of your test file to the question. If str is a character array with more than one row, sscanf reads the characters in column order. It doesn't accept flags like '-ascii', instead you should've specified the format string. I would like to read two numbers from this: 957486 5.0E+10 The sscanf function repeatedly applies formatSpec to sequences of characters in str until it either reaches the end of str or fails to match formatSpec to a sequence of characters. Textscan fails at a certain line containing the string: ' 9574865.0E+10 ' I'm reading fixed-width (9 characters) data from a text file using textscan.
