A pseudocolor plot displays matrix data as an array of colored cells (known as faces ). MATLAB ® creates this plot as a flat surface in the x - y plane. The surface is defined by a grid of x - and y -coordinates that correspond to the corners (or vertices) of the faces. The grid covers the region X=1:n and Y=1:m, where [m,n] = size(C).Create a matrix containing complex elements and compute its nonconjugate transpose. B contains the same elements as A, except the rows and columns are interchanged. The signs of the imaginary parts are unchanged. A = [1 3 4-1i 2+2i; 0+1i 1-1i 5 6-1i] A = 2×4 complex. 1.0000 + 0.0000i 3.0000 + 0.0000i 4.0000 - 1.0000i 2.0000 + 2.0000i.Changing Axis Direction. The XDir, YDir, and ZDir properties control the direction of increasing values on the respective axis.

The issue is that one of the first data points has a very large amplitude, whereas the rest of the data points have very small magnitudes. So what I thought that I wanted to do is to make a "cut" in the y-axis, such that it goes from 0..1 and then skips to 100..105.13. You can change the direction of an axis by setting the appropriate direction property, see the XDir, YDir, ZDir properties in the Axes Properties documentation. These properties have the value normal or reverse. To reverse the direction of one of your axis, say the x-axis, use. set(gca, 'XDir', 'reverse')plot(x,y) Add another sine wave to the axes using hold on. Keep the current axis limits by setting the limits mode to manual. y2 = 2*sin(x); hold on. axis manual. plot(x,y2) hold off.

Hi everybody, I'm trying to plot the price of an option against time to expiration time in days (in positive integer ofc). But I need to reverse the time.3. You can use the function flip to flip any array along one axis: Aa = flip(A,2); This will work for both a gray-scale and an RGB image. This is equivalent to the following indexing expression for a 3D array (such as an RGB image): Aa = A(:,end:-1:1,:); Tip: If you are going to write a loop, always make the inner loop the one that loops over ...Hello everyone, i am trying to code stream function in Matlab. i am done with alghoritmic part but having a problem with my contour plot.
