MATLAB: Help splitting string using strsplit

MATLABstrsplit

I have a large set of data which is presented as a string, for example:

1;2;3;4;5;6;7;8 etc…

I use:

strsplit(data,';')

and that breaks everything up into individual cells.

However I have found an issue with some data. My logger is 100% reliable so sometimes I get data which looks like:

;;;;;6;7;8 etc…

Using the strsplit command I get:

NaN 6 7 8

What I'd like is

NaN NaN NaN NaN NaN 6 7 8

Any suggestions?

Richard - from strsplit try doing the following

strsplit(data, ';', 'CollapseDelimiters', false)

so that the consecutive empty delimiters are not collapsed into one cell.

How about using regexp to find the position of spaces, and delete 2nd~Nth spaces? Like:

mystring = 'this is my string';
pos = regexp(mystring,'\s');
mystring(pos(2:end)) = [];

you can use the function regexp.

example:

~isempty(regexp('scramble3','\d'))

would return a 1.

if you leave out the isempty check then it'll return 9 which is the index position of the number.
