How to plot for for a range? showing error

Answer 1

[Bhaskar R]

Your code

t = 0:0.001:1;
D = (117649*exp(4*t))/6561- (117649*exp(4*t))/26244 - (117649*t.^2.*exp(4*t))/4374 - ...
    (117649*t.^3.*exp(4*t))/8748 - (117649*t.^4.*exp(4*t))/46656;
plot(t, D);

Answer 2

[Vladimir Sovkov]

Probably, t^2 and t^4 are implyed to be t.^2 and t.^4.

And all the multiplications of the expressions containing t are implyed to be .* but not just *

This is if you want to do the element-wise operations (as it looks to be) but not the algebraic matrix operations.
