MATLAB allows you to use your data in another application that reads ASCII files. Data export (or output) in MATLAB means to write into files. The file name is the workspace name of the cell array, appended with the extension. Good Good for fast calculations on vectors and matrices.::Bad Bad if you can not state your problem as a vectorwritecell( C ) writes cell array C to a comma delimited text file. It is heavily optimized for vector operations. 1 An introduction to MATLAB MEX-files Maria Axelsson mariacb.uu.se Maria Axelsson, Centre for Image Analysis MATLAB MATLAB (by Mathworks) is a good development platform for image analysis algorithms.

Create a script file and type the following code в€’MATLAB executes the above statements and displays the following result. ExampleThe following example demonstrates the concept. When you finish writing, close the file by calling fclose(fileID).Rectangular, delimited ASCII data file from an array.Diary (or log) file of keystrokes and the resulting text output.Specialized ASCII file using low-level functions such as fprintf.MEX-file to access your C/C++ or Fortran routine that writes to a particular text file format.Apart from this, you can also export data to spreadsheets.There are two ways to export a numeric array as a delimited ASCII data file в€’Using the save function and specifying the -ascii qualifierWhere, my_data.out is the delimited ASCII data file created, num_array is a numeric array and в€’ascii is the specifier.Syntax for using the dlmwrite function is в€’Dlmwrite('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 dlm_char is the delimiter character.

For these purposes, MATLAB provides the low-level fprintf function.As in low-level I/O file activities, before exporting, you need to open or create a file with the fopen function and get the file identifier. However, you may need to create other text files, including combinations of numeric and character data, nonrectangular output files, or files with non-ASCII encoding schemes. Exporting Data to Text Data Files with Low-Level I/OSo far, we have exported numeric arrays. The diary function creates an exact copy of your session in a disk file, excluding graphics.Optionally, you can give the name of the log file, say в€’You can open the diary file in a text editor.
