Number format coming from syms into subs leading to Excel format

2 views (last 30 days)
I have equations that use "syms" variables. After the equations are finished I want to add numbers to the final equations with "subs". These equations are in Matrix form. There are a lot of Matrices so I opted to display them in Excel.
My problem is the number format coming out of the "subs" is different then the "Double" format needed for Excel so I need a way to convert them.
My interface with Excel works flawlessly when no other errors.
rr = exlSheet1.Range(['C' num2str(5)]).value;
theta = exlSheet1.Range(['D' num2str(5)]).value;
for i=1:4
for j=1:4
for k=1:4
Affinity(i,j,k)=subs(Affinity0(i,j,k),{r,h},{rr,theta})
end
end
end
exlSheet1.Range(['I' num2str(3)]).value=Affinity(1,1,1)
exlSheet1.Range(['J' num2str(3)]).value=Affinity(1,1,2)
exlSheet1.Range(['K' num2str(3)]).value=Affinity(1,1,3)
...

Affinity(i,j,k) = double(subs(Affinity0(i,j,k),{r,h},{rr,theta}));

is there another format that is 10 decimal or (number *10^integer) instead of a double having a 2 decimal

At your MATLAB command line, what do you have
format
set to?
Are you referring to the format at the MATLAB level, or at the Excel level?
