Hi,
I have generated the graph in which there are a lot of curves generated, but I do not want to plot all of the curves -- there are 86 curves on that graph. I want to specify few curves only. I am not sure how to do it. Can anyone help?
Code:
w = [0,1,2,3,4,5,23,230,324,2130,2130,123,123,0.3242000,0.2320000,0.2232400000,0.271950151680000,0.307006225920000,0.344186910720000,0.383492206080000,0.424922112000000,0.468476628480000,0.514155755520000,0.561959493120000,0.611887841280000,0.663940800000000,0.718118369280000,0.774420549120000,0.832847339520000,0.893398740480000,0.956074752000000,1.02087537408000,1.08780060672000,1.15685044992000,1.22802490368000,1.30132396800000,1.37674764288000,1.45429592832000,1.53396882432000,1.61576633088000,1.231,1.78573517568000,1.87390651392000,1.96420246272000,2.05662302208000,2.15116819200000,2.24783797248000,2.34663236352000,2.44755136512000,2.55059497728000,2.65576320000000,2.76305603328000,2.87247347712000,2.98401553152000,3.09768219648000,3.21347347200000,3.33138935808000,3.45142985472000,3.57359496192000,3.69788467968000,3.82429900800000,3.95283794688000,4.08350149632000,4.21628965632000,4.35120242688000,4.48823980800000,4.62740179968000,4.76868840192000,4.91209961472000,5.05763543808000,5.20529587200000,5.35508091648000,5.50699057152000,5.66102483712000,5.81718371328000,5.97546720000000].'
%w = 0.00106230528000000
x = [0:0.008:3.4];
L = 3.4
E = 2.1E11
I = ((0.115465)^4)/12;
y = (((w.*x).*(L-x))/(24*E*I*L)).*(L^2+(x.*(L-x)))
plot (x,y,'Color',[0.4940, 0.1840, 0.5560],'LineStyle','-','LineWidth',1.5)
The x and w values cannot be changed. I want some sort of line saying that as plotting 1 to 86 graph.... plot 1,10,15 so on until curves on the graph

Do you want something like this?
plot (x,y,'Color',[0.4940, 0.1840, 0.5560],'LineStyle','-','LineWidth',1.5)
hold on
plot (x,1.86 * y,'b','LineStyle','-','LineWidth',1.0);
plot (x,1.10 * y,'b','LineStyle','-','LineWidth',1.0);

haha, Please see the attached script. yep, I am calculating deflection on the beam. So, basically what I am doing keeping the load same (UDL) through out the length and I have around 87 load values here, so I want to tell the code I want to plot the curves at after every 10 curves lets say start from 0, 10th(whateverload it is), 20th,30,40,50, until 87th is the last one. ratther than it plotting all of them curves.
Just looking for a sort of code line where I can specify few curves and plot only them curves

You can limit the curves by this way
close all
clear all
clc

Try setting up a vector that lists whatever rows you want to plot:
w = [0,1,2,3,4,5,23,230,324,2130,2130,123,123,0.3242000,0.2320000,0.2232400000,0.271950151680000,0.307006225920000,0.344186910720000,0.383492206080000,0.424922112000000,0.468476628480000,0.514155755520000,0.561959493120000,0.611887841280000,0.663940800000000,0.718118369280000,0.774420549120000,0.832847339520000,0.893398740480000,0.956074752000000,1.02087537408000,1.08780060672000,1.15685044992000,1.22802490368000,1.30132396800000,1.37674764288000,1.45429592832000,1.53396882432000,1.61576633088000,1.231,1.78573517568000,1.87390651392000,1.96420246272000,2.05662302208000,2.15116819200000,2.24783797248000,2.34663236352000,2.44755136512000,2.55059497728000,2.65576320000000,2.76305603328000,2.87247347712000,2.98401553152000,3.09768219648000,3.21347347200000,3.33138935808000,3.45142985472000,3.57359496192000,3.69788467968000,3.82429900800000,3.95283794688000,4.08350149632000,4.21628965632000,4.35120242688000,4.48823980800000,4.62740179968000,4.76868840192000,4.91209961472000,5.05763543808000,5.20529587200000,5.35508091648000,5.50699057152000,5.66102483712000,5.81718371328000,5.97546720000000].';
