bug saving dseries in csv format that have had operations made on them
The following results in a malformed csv file because of the commas in the names of the variables:
a=dseries(rand(3,1), '1999y', 'a');
b=a*a;
b.save('malformed','csv');
results in:
,multiply(a,a)
1999Y, 0.66377469
2000Y, 0.82045903
2001Y, 0.016125652
need to replace the second comma in the first line with something else
