i have 10 unknowns
for example d1_1 d1_2 d2_1 d2_2 d3_1 d3_2 d4_1 d4_2 d5_1 d5_2
and i would like to place them into a matrix d which
d ( : , : , 1 ) = [ d1_1 ; d1_2 ] ;
d ( : , ; , 1 ) = [ d2_1 ; d2_2 ];
. . . . . . . . . . .
is there any simpler way for me to define this d matrix?
thank you!

If you have a relatively new version of the Symbolic Toolbox (R2011b or later I think it is),
d = sym('d', [5 2])

oh i don't think i have that ;-(
so there is no other way to solve this problem?
anyway, thank you!

No. Symbolic Toolbox (or equivalent) is the only way to express unknowns.
Or is your question that you have 10 known values and you want to place them in an array?
