MATLAB: Plot a single Error bars

errorbar

Hi all,

I am trying to create one error bar but I am struggling a lot.

I tried to read the matlab documentation about error bars but the site is down for some reason.

Anyway, I have calculate the standard deviaiton (s=4.13) but I am confused witht the x,y axes

the x axis should be 1 value and the y axis has a range from 0 to 14

please let me know what you think

many thanks

Nikolas

Hi,

Bar chart can be created by making use of bar and errorbar functions as shown in the following code.

x=1; y=8.35;
sd=4.13;
bar(x,y);
hold on
errorbar(x,y,sd)
ylim([0 14])
xticks([0:2])
hold off

Output:

Please refer the following link for further information on errorbarfunction

Hope this helps

MATLAB: Plot multiple errorbars in pairs

To locate the center of each grouped bar, use the undocumented bar object property, "XOffset" which is the horizontal offset of each bar-center from the group index value.

xCnt are the bar centers.

error=[3.3 2.1;1.1 4];
x=[1:2 ;1:2]'; 
y=[3.5 2.2; 5.2 3.3];
h = bar(x,y)
hold on
% Get bar centers
xCnt =  h(1).XData.' + [h.XOffset]; 
% Alternative: xCnt = get(h(1),'XData').' + cell2mat(get(h,'XOffset')).'; % XOffset is undocumented
errorbar(xCnt(:),y(:),error(:),'*')  % <--- If you want 1 errorbar object
% errorbar(xCnt,y,error,'*')         % <--- If you want separate errorbar objects, 1 for each bar-group
% errorbar(...,'k*') to make the errorbars black (which is better than yellow)
ylim([-8 18])
xticks([1:2])
hold off

MATLAB: How to define an arbitrary constant for equations

If you are talking about making an assumption, you can do it as follows:

v1=6;
v3=18;
syms v2 v4 v5 v6
eqn1= -v4+v5==-v3;
eqn2= -v2+v6==v3;
eqn3= -v5-v6==-v1;
assume(v6~=0)
[v2 v4 v5 v6]=solve(eqn1, eqn2, eqn3);
[v2 v4 v5 v6]
