#Scilab matrix how to

Let’s see how to get sensors IDs (2341 and 453) and coordinates ( and ).įirst of all, import text within a SCILAB matrix, using default csvRead function, settings for separators (' ') and decimals ('.') and forcing conversion to string (see image above). This file is mainly about text information but is also providing a few quantitative information regarding some sensors. If we take the example of Data1.txt file (see Var - A image above).

#Scilab matrix full

You did manage to import your data within SCILAB (did you?) however you got the full text as an array of string instead of the needed data (what could be provided by csvRead function with string conversion or mopen/ mgetl). Now let's say we are in the worst case scenario. In the case of Data1.txt file, this function is providing the same output as the csvRead function. Whenever your script run into an error and do not reach the mclose command line, you will have to close your file manually ( > mclose(id) in the console) otherwise you won't be able to access your file until SCILAB releases it. Use mopen function to open the text file (see help for different options), use mgetl function to get all the lines as array of strings and DO NOT FORGOT TO CLOSE YOUR FILE using mclose function. In those critical case there is one last solution. Sometimes, text files are following the physical law of thermodynamics (especially the second one). When nothing else is working: mopen/ mgetl

For the third one which is a CSV file, we specify separator (' ') and decimal (',') as well as range of data to be imported: from line 2 to 5, from column 2 to 4.

This allows us to make direct conversion of data into double (default).

For the second one we already saw, we specify tghe number of lines at the beginning of the file to be ignored: 1 corresponding to the header.

For the first one which mainly about characters, we impose a conversion to string waiting for the full file to be further processed within SCILAB.

In this case, we are reading the three text files provided in the zip archive. or when fscanfMat is not working, you can use the csvRead function. ), or you want to access CSV data (coming from an excel file for example). When you are looking for more flexibility (selecting range for rows and columns, conversion into double/string. But as you will experience it, this function is not suitable for every text file.
