MATLAB: Way to plot multiple lines in 3d specifying start and end point

3d plotslineMATLABplot

Is there a way to plot multiple lines on 3 axis and specify the start and end point

This is a crude example but something like Line Start (x,y,z) Line To (x,y,z)

P0 = rand(7,3) ;
P1 = rand(7,3) ;
X = [P0(:,1) P1(:,1)] ;
Y = [P0(:,2) P1(:,2)] ;
Z = [P0(:,3) P1(:,3)] ;
plot3(X',Y',Z')
hold on
plot3(X',Y',Z','.')

MATLAB: How to determine each local min point

If you have the Image Processing Toolbox, you can use imregionalmin(), like this:

% Original code
x = 0: 0.00001: 4;
v = x.*exp(x/2);
t = sin(v);
plot(x,t);
% Image Analyst's code:
minsIndexes = imregionalmin(t); % Logical array of where mins are.
% Extract the t values at those min locations;
minValues = t(minsIndexes) 
% Get the x values at those mins.
minX = x(minsIndexes) 
% Plot star over the mins.
hold on;
plot(minX, minValues, 'r*', 'MarkerSize', 10);

In the command window:

minValues =
             0         -1.00         -1.00         -1.00         -1.00         -0.96
minX =
             0          1.86          2.76          3.31          3.70          4.00
