Matrix number format not a double
显示 更早的评论
I need to format not with a double :
number * 2^(integer)
but with a base 10 format :
floatingpointnumber * 10^(integer)
or
(floatingpointnumber)E(integer)
for i=1:4
for j=1:4
for k=1:4
Affinity(i,j,k)=double(subs(Affinity0(i,j,k),{r,h},{rr,theta}))
end
end
end

fprintf('%.10e %.10e %.10e %.10e\n', Affinity)
or
format f
disp(Affinity)

double() already creates the values as floating point numbers. When you use double() the internal storage will be IEEE 754 Binary Floating Point "double", 64 bit.
Anything like floatingpointnumber * 10^(integer) is a matter of display not of storage. I have shown you two different ways to change the display.
However, as long as you do not initialize your Affinity matrix to a floating point number such as 0, then you can convert your value to a symbolic number that would display the way you are looking for. To do that, change double() to vpa(). Note that the values so created will look as if they are normal MATLAB arithmetic values but will instead be symbolic numbers.
