MATLAB: Concatenation

concatenation

Hi Everyone!

Hi would like to concatenate the entries of non-negative matrix into one single number! is that possible? any Ideas?

Here is an example:

a=[6 0 11; 15 5 10; 10 12 13]

and I want it to become:

a=[6011;15510;101213]

any suggestions?

Thank you in advance! all the best!

a = str2double(arrayfun(@(x)sprintf('%d',a(x,:)),(1:size(a,1))','un',0))

variant

a = str2double(regexprep(cellstr(num2str(a)),' ',''))

With col1, col2, and col3 being column vectors:

fmt = ['%f %f %f\n' repmat('%f %f\n', 1, 99)];
fid = fopen('YourOutputFile.txt', 'wt');
fprintf(fid, fmt, col1(1), col2(1), col3(1), [col1(2:end), col2(2:end)].');
fclose(fid);

Warning: the details of the fprintf() call depend upon col1 and col2 being column vectors!

It is always possible to go the long way around here.

a = {11.741667 3.913892 14.488700 8.746350 0.349066};
str = cellfun(@num2str,a,'un',false);
str = strrep(str,'.','');
myStream = horzcat(str{:});
