#Matlab open a file txt write code
Create a script file and type the following code − The following example demonstrates the concept. Where, my_data.out is the delimited ASCII data file created, num_array is a numeric array and dlm_char is the delimiter character. Syntax for using the dlmwrite function is −ĭlmwrite('my_data.out', num_array, 'dlm_char') Where, my_data.out is the delimited ASCII data file created, num_array is a numeric array and −ascii is the specifier. Using the save function and specifying the -ascii qualifier There are two ways to export a numeric array as a delimited ASCII data file − MEX-file to access your C/C++ or Fortran routine that writes to a particular text file format.Īpart from this, you can also export data to spreadsheets. Specialized ASCII file using low-level functions such as fprintf. Rectangular, delimited ASCII data file from an array.ĭiary (or log) file of keystrokes and the resulting text output. You can create the following type of files − For this, MATLAB provides several data export options. MATLAB allows you to use your data in another application that reads ASCII files. I can't go back and edit my above post anymore so hopefully it doesn't confuse anyone else.Data export (or output) in MATLAB means to write into files. csv for delimited files around here.Īnyway, to the OP and anyone else, this is apparently a setting on my machine that I made several years ago and forgot. It's funny because I basically never use the tdl file extension, so I wouldn't have a reason to set it up to open in Excel automatically. I must be getting mixed up with csv, which I think Excel will open natively (but who knows, I could've made that setting years ago and forgotten too). My Excel does recognize *.tdl files but I can't for the life of me remember setting that up. Well it looks like I owe the forum an apology, you're right. Otherwise, I have Ultra Edit set the tabs fairly large so my columns usually line up. I typically just open Excel and then drag my files over if I really need to do something with them in Excel.
#Matlab open a file txt write windows
So I'm guessing you configured Windows to open a tdl file with Excel. I just changed one of my data files to a tdl extension and now Windows has no clue what to do with the file. So "Force" would be followed by 11 here, but Excel will open automatically with a. Any missing characters would be filled with spaces. So a format code of %-16s would take any string up to 16 characters. You could send the data out with string formatting codes that are fixed some over places. If it is just to display the data in some text window and you don't care about extra characters screwing things up, first you need to make sure that text window is set up some monospaced font like Courier. Doing anything will just complicate the parsing of the file in to data.
If it is to programmatically read the file and analyze, don't worry about appearance. The problem is that if your title is dramatically different in length from your data element, enough that one or the other reaches beyond the arbitrary tab stop of whatever program you are using the data, it is never going to appear the way you want. In your shown example, your appearance is based on the HTML formatting of the NI website.
I think you are confusing appearances with data representation. It is certainly different between Notepad and Word (where the distance between tab stops is a formatting property.) Heck that may even vary from application to application. The OS defines how many "spaces" a tab takes up upon display. This is not a LabVIEW issues, but an OS issue.
