Problem 1981. Time and Variable mapping and matching

Created by Chintan in Community

There is a 6X5 cell array where

1st column represents time values
2nd and 3rd column represent variables and their values respectively
4th and 5rd column represent variables and their values respectively

Note that same variable can be used in columns 2 and 4, but not in same rows Sample cell array is shown below:

 X = 
 {'0','a','1', '', '';
  '1','b','2', '', '';
  '2', '', '','c','3';
  '3', '', '','d','4';
  '4','e','1','' , '';
  '5', '', '','d','6'};

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:

 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

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));

Done. Many Thanks.

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.
