MATLAB: How to plot for for a range? showing error

error in multiplication sign. i am trying to plot against t=0 to 1

Best Answer

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);

MATLAB: Plotting error: Need to plot the evolution of symbolic matrix

Try this:

PHI = @(t) [ 1, t, t/3-(2*exp(-3*t))/9+2/9, (2*t)/3+(2*exp(-3*t))/9-2/9;
    0, 1, (5*exp(-3*t))/12-(3*exp(t))/4+1/3, 2/3-exp(t)/4-(5*exp(-3*t))/12;
    0, 0, exp(-3*t)/4+(3*exp(t))/4, exp(t)/4-exp(-3*t)/4;
    0, 0, (3*exp(t))/4-(3*exp(-3*t))/4, (3*exp(-3*t))/4+exp(t)/4];
N = @(t) norm(PHI(t));
t = linspace(0, 1, 50);
for k = 1:numel(t)
    Nt(k) = N(t(k));
end
figure
plot(t, Nt)
grid

MATLAB: Display maximal value in a range

I do not see any max function calls, so I am not certain what result you want.

Displying only the values for ‘tv’ between 7 and 10 is straightforward:

Lidx = (tv>=7) & (tv<=10);
figure
plot(tv(Lidx),sigmav(Lidx),'b',tv(Lidx),sigmadotv(Lidx),'r')

with ‘Lidx’ being the logical index vector. This will select the values of the vectors you want.

To display ‘max(abs(sigma))’, assuming you intend ‘sigmav’:

maxSigma = max(abs(sigmav(Lidx)))
maxSigma =
     4.451070235722554e-07

If you simply want to restrict the plot, you can also do that with the xlim function.

If you want to display it on the plot, use the text function.
