    Plotting Excel Data in Matlab: How to Combine Multiple Rows into One Figure

    Yes these are coordinates of points inside the circle. I know plot3 but that just creats circle. i want these coordinates inside the circle.

    Plotting Excel Data in Matlab: How to Combine Multiple Rows into One Figure

    I have 4 sets of data of points with x,y,z coordinates in an excel file I want to plot all the data points in one plot and I want all these points to be inside a circle.

    Eelipsoid and line intersection

    i need the point A to be inside . I guess I should have given the arbitraty values for the axis as a=3 b=2 and c=1 . I hope a,b,c are the semimajor axis,semiminor axis and the z axis repectively in the ellipsoid equation . and the coordinates of A(1,2,3) are separate. the point on the...

    Eelipsoid and line intersection

    Thank you for your responce. I used a=1 b=2 c=3 for coordinates of A(1,2,3) and center(0,0,0) now my equaation becomes for point p(x,y,z) on ellipsoid x=0+(1-0)t=t y=0+(2-0)t=2t z=0+(3-0)t=3t put in ellipsoid equation t^2/1+4t^2/4+9t^2/9=1 3t^2=1 t=sqrt(1/3)=.57 x=.57...

    Eelipsoid and line intersection

    Thank you very much . I tried that method but the problem I am facing is say my point A (1,2,3) is inside the ellipsoid and center(000) and the point on the ellipsoid i solve using x^2/a2+y^2/b2+Z^2/c^2=1 by substituting x=t,y=2t,z=3t and solving for t. But the distance between center and...

    Eelipsoid and line intersection

    Homework Statement I have an ellipsoid with center (000). There is a point A inside the ellipsoid with known coordinates(1,2,3) I draw a line from center to point A and extend it to cut the ellipsoid on on point p(x,y,z). Homework Equations I want to find the...

    Find the coordinates of the point on the ellipsoid where the major axis meet

    but " a" is not a point. see the coordinates of p and center are given. length of axis and components are given. I am not sure if I can consider components of vector A to be coordinates.Then I can use the cosine formula for the triangle.

    Find the coordinates of the point on the ellipsoid where the major axis meet

    Homework Statement I have a point p(xp,yp,zp) inside an ellipsoid and i want to find the angle of that point from the center of the ellipsoid(xc,yc,zc) . I also have the major axis length 'a' ,with length ax,ay and az components I calculated the unit vector of axis a with formula...
