The MSDN documentation for the String.Split Method lists six overloads for this method. But if I do not have a string, I cannot access it. This means that when I have a string, I can gain access to the Split method. The Split method from the System.String class is not a static method. In fact, I got a rather nice oolong tea in little triangle sachets that is actually not bad. On the bright side, I did pick up some nice tea bags when the Scripting Wife and I were in Europe, so it is not a total loss. And of course, my various tins of teas and herbs are sitting here, just waiting for me to locate the teapot. It is not a major crisis yet, but I do miss blending my own teas with my own herbs. At least I found my kettle to heat water so I can make tea, but unfortunately, without a teapot, I am stuck drinking “bagged” tea leaves. Dude, dude, dude, (or dudette, as the case may be) I still cannot find my teapot after our move. Microsoft Scripting Guy, Ed Wilson, is here.

Summary : Microsoft Scripting Guy, Ed Wilson, talks about using the Split method in Windows PowerShell. Out_sep = out(matches_idx>bound_idx(n) &. %// Separate out lines based on the earlier set bounds %// Finally reshape into a format with 3 numbers per row as final output %// Select only non-empty cells and convert them to a numeric array. %// Collect all cells data into a 1D cell array Split_data = regexp(data(matches_idx),' ','split')
%// Split selected lines based on the delimiter " " %// Select lines that start with character " " and split lines based on it %// Find boundaries based on delimiter "%example"Įxmp_delim_matches = strcmp(data(1),' '),1:numel(data))) This could be one approach assuming a uniformly structured data (3 valid numbers per row) - %// Read in entire text data into a cell array

If this is not the case, then my code will not work. I am assuming that your text file only has numbers delimited by characters if we encounter a line that starts with. The end result of this entire code will give you numeric arrays that are based on what you are looking for stored in nums. We then place this array into a single cell stored in nums. The resulting output of cellfun will give you a numeric array representation of each value delimited by the character for that line. You can either use a loop to go through each cell, or you can conveniently use ( to allow you to go through each element in this cell and convert the string representation into a numeric value. You need to convert this cell array back into a numeric array, and so what you would need to do is apply str2num to each element in this cell. The result of this will be a cell array of strings where each element is the string representation of your number. If it is, then we take a look at the second character until the end of this line, and split the string based on the character with strsplit. Else, we check to see if the first character is. If we read a -1, this means we have reached the end of the file, so get out of the loop. Now, until we reach the end of the file, get one line of text starting from the top of the file and we proceed to the end.
Next, we declare an empty cell array called nums which will store our numbers that you are getting when parsing your text file. We check to see if the ID returned from fopen is -1 and if that's the case, we couldn't find or open the file so spit out an error. We first use fopen to open up the file for reading. Let's assume your text file is stored in text.txt: fid = fopen('text.txt') Because you will probably have each line containing a different amount of numbers, let's store each array into a cell array where each element in this cell array will contain the numbers per line. You will receive a cell array of strings, so you'd have to convert this into an array of numbers. With each line, you check to see if the first character is a semi-colon and if it is, split up the string by the delimiter from the second character of the line up until the end. A brute force approach would be to open up your file, then read each line one at a time.
