Matlab: Save workspace to text file

In Matlab you can easily save workspace to a mat file. If you want to write workspace variables to a text file:

	clc; clear all
	vector13 = [1/3 2.1 3.1];
	vector31 = [1 2 3]';
	matrix33 = [11 12 13;...
	21 22 23;...
	31 32 33];
	scalar = 3;
	% Create a text file containing workspace variables.
	varNames = who; %List of variable names in workspace in alphabetical order.
	fileName = 'workspace.txt';
	delete(fileName);
	fid = fopen(fileName, 'a');
	for i=1:length(varNames)
	sizeOfVar = size(eval(char(varNames(i))));
	fprintf(fid, '%s : %s = ', char(varNames(i)), num2str(sizeOfVar, '%d, %d'));
	valStr = num2str(eval(char(varNames(i))),'%1.15f ');
	for iRow = 1:sizeOfVar(1)
	fprintf(fid, '%s ', valStr(iRow,:));
	end
	fprintf(fid, '\n');
	end
	fclose(fid);
