There is a 6X5 cell array where<ul><li>1st column represents time values</li><li>2nd and 3rd column represent variables and their values respectively</li><li>4th and 5rd column represent variables and their values respectively</li></ul>Note that same variable can be used in columns 2 and 4, but not in same rows
Sample cell array is shown below:<pre> X = 
 {'0','a','1', '', '';
 '1','b','2', '', '';
 '2', '', '','c','3';
 '3', '', '','d','4';
 '4','e','1','' , '';
 '5', '', '','d','6'};</pre>Output should be variables with name of variables used in array along with Time variable (1st column). Default Values of these variables (a,b,c,d,e) will be 0 at time = 0 (except if it is explicitly set eg: a=1 at time=0). Variables will continue to hold the set values except when they are explicitly set. Output of above example will be 1-D column vectors of time, a, b, c, d, e with following values:<pre> Time	a	b	c	d	e
 0	1	0	0	0	0
 1	1	2	0	0	0
 2	1	2	3	0	0
 3	1	2	3	4	0
 4	1	2	3	4	1
 5	1	2	3	6	1</pre>

suggestion: please change the testsuite line that reads "assert(isequal(your_fcn_name(x),y_correct))" to [Time,a,b,c,d,e]=your_fcn_name(X); assert(isequal([Time;a;b;c;d;e],y_correct));

Chintan on 12 Nov 2013

Done. Many Thanks.

Alfonso Nieto-Castanon on 12 Nov 2013

I believe you still would need to add back the line "y_correct=[Time;a;b;c;d;e];" right before the line "[Time,a,b,c,d,e]=your_fcn_name(X);" for the testsuite to work?

Sorry, my mistake.Thanks.
