How do you calculate francis turbine hill curves using matlab?
To calculate Francis turbine hill curves using MATLAB, you typically start by defining the turbine parameters, including flow rates and head values. You can then create a function that models the turbine performance based on the specific speed and efficiency. Using the plot function, you can visualize the relationship between head and flow rate to generate the hill curves. Additionally, you might use optimization techniques to refine the performance predictions based on operational conditions.
How do you make graph from an equation in Matlab?
Initially, the equation can be directly realized using Matlab source code. Then various inputs can be applied to it. These values can easily be plotted on a graph using plot or stem command in Matlab.
How can I plot a PDF in MATLAB?
To plot a Probability Density Function (PDF) in MATLAB, you can use the "histogram" function with the 'Normalization' parameter set to 'pdf'. This will create a plot that represents the PDF of your data.
How do you plot frequency spectrum using fft function in MATLAB?
plot(abs(fft(vectorname)))the FFT function returns a complex vector thus when you plot it, you get a complex graph. If you plot the absolute value of the FFT array, you will get the magnitude of the FFT.
How do you add of two signal in matlab?
To add two signals in MATLAB, you can simply use the plus operator (+). For example, if you have two signals stored in arrays signal1 and signal2, you can add them together using result = signal1 + signal2;. Ensure that both signals have the same length; otherwise, MATLAB will return an error due to dimension mismatch. After adding, you can plot the result using the plot function for visualization.
How do you plot Dirac function in MATLAB?
To plot each value of a vector as a dirac impulse, try stem instead of plot.
What is a stem in matlab?
stem(x) will plot a graph in discreet form
What is stem in matlab?
stem(x) will plot a graph in discreet form
How exactly does MATLAB plotting work?
MATLAB is a software program that helps people with doing math. More specifically, it helps people with visualization, programming, and computation. MATLAB plotting should be done in plot edit mode.
What is the Matlab code to plot a histogram?
imhist(x); where 'x' is your data or image to find histogram.
How can one graph indifference curves from utility functions?
To graph indifference curves from utility functions, you can plot different combinations of two goods that give the same level of satisfaction or utility to a consumer. Each indifference curve represents a different level of utility, with higher curves indicating higher levels of satisfaction. By using the utility function to calculate the level of satisfaction at different combinations of goods, you can plot these points to create the indifference curves on a graph.
How do you expand the axis limits in MATLAB?
after you plot, type axis([xmin xmax ymin ymax]) and that should do it.
