I am trying to use this
xDataNumbers = [2.5 5 7 8 11.5]
as the datanames for a fints
tsobj = fints(dates, data, datanames)
so - the question is: How do I convert a vector with numbers into a "Cell array of data series names" in the form nn.n?
The third input to the fints function is a cell array of strings that can be valid MATLAB identifiers. That is, the strings cannot start with numbers and can only contain letters, numbers, and the underscore. As a workaround, you could do this
% convert numeric array to cell, and convert all contents to strings dataNamesInput = cellfun(@num2str,num2cell(xDataNumbers(:)),'uniformoutput',false);
% make sure first letter is not numeric (it will be 'x') dataNamesInput = cellfun(@(s)['x',s],dataNamesInput,'uniformoutput',false);
% remove periods and replace with underscores dataNamesInput = regexprep(dataNamesInput,'\.','_');
and use dataNamesInput as the third input. Someone may suggest using the genvarnames function, but it will replace periods with '0x2'. You may prefer that. In any case, you'll still need the first line of code above that converts numeric array to cell of strings.
