How can I express all the variables Vcm1, Vcm2, Vcm3, Vcm4 in num2str without getting an error?

annotation('textbox',dim,'String',((num2str(Vcm1),num2str(Vcm2),num2str(Vcm3),num2str(Vcm4)), 'FontSize';15)

I'm trying to represent the center of mass velocities in a 4-link model, so I want my center of mass velocities to be seen in my animation through num2str, I already have my values defined for each velocity but I just want to know what commands apply so that the 4 speeds are seen on the graph

Ran in:
Dont know what exactly you are trying to do but here is an example using your variable names:
dim = [0.2 .5 0.25 0.1];% normalized dimensions
Vcm1 = 1.05;
Vcm2 = 2.05;
Vcm3 = 6.52;
Vcm4 = -2.56;
myText = sprintf('%.2f, %.2f, %.2f, %.2f',Vcm1,Vcm2,Vcm3,Vcm4);
figure(1)
plot([0 10],[0 10])
annotation('textbox',dim,'String',myText, 'FontSize',8)

Yes, I have exactly a similar example but I didn't know how to express the four velocities of the center of mass in num2str because I want to represent them in my animation of the velocities, but that command came out as an error
