I want to Wrap angles to the range [-180, 180] degrees. For this I have the following code:
function wrapped_angles = wrapTo180(angles)
% Wrap angles to the range [-180, 180] degrees
wrapped_angles = mod(angles + 180, 360) – 180;
end
Likewise, I want Wrap angles to the range [-90, 90] degrees. For this I have the following code:
function wrapped_angles = wrapTo90(angles)
% Wrap angles to the range [-90, 90] degrees
wrapped_angles = mod(angles + 90, 180) – 90;
end
The 2nd function works correctly but the 1st one doesn’t work correctly. Why it is so?I want to Wrap angles to the range [-180, 180] degrees. For this I have the following code:

Hi,
There is node from A to H and used shortestpath fn to find the short path
a=["A" "A" "A" "B" "B" "C" "C" "D" "D" "E" "F" "F" "G"];
b=["B" "C" "D" "D" "F" "D" "E" "E" "G" "G" "G" "H" "H"];
distance=[3 2 5 2 13 2 5 4 3 6 2 3 6];
c=digraph(a,b,distance)
plot(c,’EdgeLabel’,c.Edges.Weight)
[p,d]=shortestpath(c,"A","H")
got this
c =
digraph with properties:

Edges: [13×2 table]
Nodes: [8×1 table]

p = 1×5 string
"A" "C" "D" "G" "H" *

d = 13

But i need to have results from A to B , A to C ,…. till A to H. I have used shortestpathtree but gives only edges and nodes with distance. I need result like above one ‘p’ with multiple target nodes (with single source node). is that for loop helpful? else any other way.
Thanks in advance.Hi,

Hi,
i am currently trying my first major project in Simscape (delta robot).
I want to adjust the angles of the joints RevoluteJoint2, 3 and 4 via three inputs. When I do that I get the mentioned error. If all joints have the same input value, no error occurs.
Can someone tell me why the error occurs? Thank you.
Project:
Is attached.
Error message:
"An error occurred while running the simulation and the simulation was terminated
Caused by:
[‘untitled_ohneCad/Solver Configuration’]: Model not assembled due to a position violation. The failure occurred during the attempt to assemble all joints in the system and satisfy any motion inputs. If an Update Diagram operation completes successfully, the failure is likely caused by motion inputs. Consider adjusting the motion inputs to specify a different starting configuration. Also consider adjusting or adding joint targets to better guide the assembly."Hi,

My App Designer program uses USB communication to an Arduino
It usually works but every once in a while Matlab fails to read.
configureCallback(app.PicoCom,"terminator",@app.PicoInput);
…
function PicoInput(app,src,~)
% check if there is more than 1 line. For some reason I don’t get another callback!!!
while (app.PicoCom.NumBytesAvailable>0)
raw = readline(src);
I’ve already added the while loop which mostly fixed it except if the messages are 20msec apart.
The only time it fails (and not very often) is between 2 messages that are known to be 20 ms apart.
When it fails (App Designer says "Run" … no action), I can go into the debugger (with a special pause I put in to read app properties) and check with
K>> app.PicoCom
ans =
Serialport with properties:
Port: "COM6"
BaudRate: 57600
NumBytesAvailable: 11
K>> read(app.PicoCom,11,"char")
ans =
‘z73851718
‘
And there it sits, not being read.
Sure, there are probably work arounds (I’m open to suggestions to manage it now) but isn’t this a bug!
My next attempt to handle this is to add a pause(0.03); at the end of the while loop but this is very unsatisfying and how do I know it will NEVER fail?My App Designer program uses USB communication to an Arduino

Hi!

I have a matrix of data with only 0 and 0.2 values. I need to have the sum of successive 0.2 values (delta) for each columns of my matrix. Example: col1= 0 0 0 0.2 0.2 0.2 0.2 0 0 0.2 0 0.2 0.2 and the result_col1= 0.8 0.2 0.4. I write a script that works very well to do this (see above). First little problem, how can I say to my script that you need to read all columns of my matrix and put each correspondant delta values in my final matrix d?

Then, I would like to have a rule saying to the script "when you saw less than five zeros successively don’t stop to calculate delta". In my script, the calculation of delta stop when the script saw only one zero after a 0.2 value.

Thanks a lot.
Julien
