You can use octave instead (this is a free and open clone of matlab). You can assess your ODE system by a vector function such as: function dx = f(x,t) dx(1) = x(2) - x(1); dx(2) = x(1)*(4-x(2)); end Then you can solve it using lsode method for a given set of initial condition on a defined time range: xs = lsode(@f,[1,2],0:0.01:10); You can also plot the vector field associated with the system using quiver function. Printing xs over it give you the trajectory for the initial conditions you have chosen.
By plotting several trajectories you will get a preciser idea of phase diagram associated with. The following plots have been produced with octave using the above procedure.
Which software is most suitable in preparing ternary phase. Is there any good open source program to plot ternary phase diagrams? How to calculate.
Approximate colours of Ag–Au–Cu alloys in jewellery making In a ternary plot, the proportions of the three variables a, b, and c must sum to some constant, K. Usually, this constant is represented as 1.0 or 100%. Because a + b + c = K for all substances being graphed, any one variable is not independent of the others, so only two variables must be known to find a sample's point on the graph: for instance, c must be equal to K − a − b. Because the three proportions cannot vary independently—there are only two —it is possible to graph the combinations of all three variables in only two dimensions. Contents • • • • • • • • Reading values on the ternary plot [ ] The advantage of using a ternary plot for depicting is that three variables can be conveniently plotted in a two-dimensional graph.
Ternary plots can also be used to create by outlining the composition regions on the plot where different phases exist. Every point on a ternary plot represents a different composition of the three components. A parallel to a side of the triangle is the locus of points representing systems with constant in the component situated in the vertex opposed to the side. There are three common methods used to determine the ratios of the three species in the composition. The first method is an estimation based upon the phase diagram grid. Alice Monteiro De Barros Curso De Direito Do Trabalho Pdf. The concentration of each species is 100% (pure phase) in each corner of the triangle and 0% at the line opposite it.
The percentage of a specific species decreases linearly with increasing distance from this corner, as seen in figures 3–8. By drawing parallel lines at regular intervals between the zero line and the corner (as seen in the images), fine divisions can be established for easy estimation of the content of a species. For a given point, the of each of the three materials in the composition can be determined by the first. For phase diagrams that do not possess grid lines, the easiest way to determine the composition is to set the altitude of the triangle to 100% and determine the shortest distances from the point of interest to each of the three sides. By, the distances (the ratios of the distances to the total height of 100%) give the content of each of the species, as shown in figure 1. The third method is based upon a larger number of measurements, but does not require the drawing of perpendicular lines. Straight lines are drawn from each corner, through the point of interest, to the opposite side of the triangle.
The lengths of these lines, as well as the lengths of the segments between the point and the corresponding sides, are measured individually. Ratios can then be determined by dividing these segments by the entire corresponding line as shown in the figure 2. (The sum of the ratios should add to 1).
