Convert a single char array to a vector of doubles with a non-whitespace delimiter [R2017b, Windows7]

Hi,

I have a binary file that when I load up into Matlab produces the following cell which contains a cell array called data:

1x1 cell array:
{'44.565,433.4544,34.332'}

This can be a very long list of numbers and I would like to avoid using str2num (which works fine). I have tried using:

slope = sprintf('%s,',data{:})
doubleArray = sscanf(slope, '%f')

This only give me the first number. I suspect this is because I have a ',' as a delimiter and not a whitespace character.

str2double(data)

returns a NaN and I suspect this is because I have a single char array in a cell and not an array of strings.

Any advice as to how to do this without str2num?

Cheers, TJ

Using sscanf is most efficient:

sscanf(a{1}, '%f,')

a={'44.565,433.4544,34.332'};
str=a{1}(:);
strNum=str2double(strsplit(str.',','))

Thanks to Stephen Cobeldick, another and faster approach:

sscanf(a{1}, '%f,')

Thanks, that worked great. I also found that the following works:

strNum = sscanf(a{:}, '%f,')

My pleasure and you had multiple options, perfect!
