    Profile of a Surface on a Honeycomb Composite Core

    The profile is being applied to a plane that intersects the walls of the honycomb core at an angle. The desired effect is to control the imaginary sloped plane which in essence is only a true surface every .182 in for ~.005 in. At the edge of every intersected cell of the honeycomb. This...

    Profile of a Surface on a Honeycomb Composite Core

    Does the Profile of a Line or Surface have any special interpretaion when it comes to composite core. I have a coworker telling me that the profile of a line or surface tolerance can be measured at any point along the line/surface. This creates an issue with our attempt to define the profile of...

    "repeating sequence" block dysfunction

    Did you try the signal generator block? It might force a system step size necessary to allowfora true square wave.

    "repeating sequence" block dysfunction

    With the repeating sequence block you enter two vectors one for y-positions and one for time. So, [0,1,1,0] [0,1,2,3] creates a trapazoid pulse signal where as [0,0,1,1,0,0] [0,1,1.001,2,2.001,3] creates more of a square pulse signal Using the repeating sequence to do a square waves is not...

    Switch statement with cell arrays

    Can't you use an if statement. if (i>=4) && (i=<100) display('?') else break Or somehting to that effect. That do what you are looking for? BsK

    how to know the current m-file directory in the mfile

    o.O Use / instead of \ try something like cd('c:/path') textread('filename') This what you needed? BsK

    Changing a variable to the subject of an equation?!

    O.o syms h,A,r solve('A=2*pi*r*h+pi*r*r',r) That do what you were looking for? BsK

    Matlab embeded function

    The basic answer as to how to simulate a pump in simulink is to write the system of equations that defines the relationship between the input, voltage or torque or force, given to the pump and the output, pressure or flow. Then translate the equations into a hand written block diagram. From...

    Non linear solver

    Marco83, I read through this and think that the output: "Optimization terminated: first-order optimality is less than options.TolFun." Is how matlab tells the user that the fsolve function has completed its solution. You can read more here , but I think that if you use the optimset...

    Changing a variable to the subject of an equation?!

    Are you trying to ask how to solve a system of equations like the following? The problem below is to solve for the acceleration vector components of a fluid particle in a fluild velocity field defined by, u=z+t v=xy+3t w=x^2*2y*t/2 This would be done by solving the following equations...

    Free standing entity in SimMechanics?

    sboyce, I dont think simMechanics is appropriate for modeling the mobility of a 4 wheel vehicular platform. It is more suited to the modeling of linkage type mechanisms where at least one support can be a ground fixed revolute joint. I would think a simulation for the mobility could be...

    m file and differential equation

    The formating of you post is off on my computer so I am not exactly certain how to answer your question. Try reading this as it might help. If it doesnt maybe post your code so that members of this forum can see what is going on, but be sure to post it with in the "unction y = mydiffeq(n) x(-1)...

    fprintf

    Hoopz just curious.. What was your delimiter with dlmwrite? How long did it take for the script to write out the identifiers? BsK

    Reading from .mat files

    I am guessing you want to extract the data for a report or to manipulate it more. To bring it into Matlab read this. Then if you wish to export it to an exel file read this or get this script I hope this helps BsK

    Simulation question

    sboyce, I read what you posted in the Matlab forum. This package might help though I have never personally used it. I suggest you try to model the dynamic response of the robot to disturabances from the ground with what you have before you attempt to buy something to do it for you. BsK

    fprintf

    You can use this, dlmwrite(filename, M, '-append'). This way you can write your header with a seperate function and then you dlmwrite to drop the whole matrix in underneath it. you can read more here Hope this helps. BsK

    Simulation question

    Have you looked at this. Or do you have a specific solution that you were hoping to find in an add-on. BSK
