Greetings

when i run this comman

plot(t_010_tbc_r_002,stress_010_01,'-o','MarkerIndices',1:10:length(stress_010_01))

it gives me this error

Error using plot
There is no MarkerIndices property on the Line class.
Error in Results (line 194)
plot(t_010_tbc_r_002,stress_010_01,'--o','MarkerIndices',1:10:length(stress_010_01))

reasons???

It does not seems to be wrong.

Run the following code and see if it works fine:

x = linspace(0,10);
y = sin(x);
plot(x,y,'-o','MarkerIndices',1:5:length(y))

same error

Error using plot

There is no MarkerIndices property on the Line class.

Error in New_Curve_02 (line 3)

plot(x,y,'-o','MarkerIndices',1:5:length(y))

The MarkerIndices name-value pair is relatively new.

If you do not have it, it is straightforward to do that with a second plot call:

figure
plot(t_010_tbc_r_002,stress_010_01,'-b')
hold on
plot(t_010_tbc_r_002(idx),stress_010_01(idx),'ob')
hold off

Experiment to get different results.

Thank you very much Star Strider. It works.

figure
plot(t_010_tbc_r_002,stress_010_01,'-b')
hold on
plot(t_010_tbc_r_002(1:10:length(t_010_tbc_r_002)),stress_010_01(1:10:length(stress_010_01)),'ob')
hold off
