How do I create a graph of y = x^2 + x + 1 in Matlab?
Where I could create the above math graph in Matlab (please see below image)?
Where I could create the above math graph in Matlab (please see below image)?
x=[-5:0.2:5];
y=x.*x+2*x+1;
plot(x,y);
soarce said:Type in command window the following:
Code:x=[-5:0.2:5]; y=x.*x+2*x+1; plot(x,y);
soarce said:You can remove the factor of 2, I put it by mistake.
Anyway, you would better start a free tour of Matlab documentation.
This command tells MATLAB to create a vector called "x" with initial value -5 and final value 5 with intermediate values spaced .02 units apart.basty said:What is the meaning of below code?
x=[-5:0.2:5];
To create a basic graph using Matlab, you can use the "plot" function. This function takes in two arrays of data, one for the x-axis and one for the y-axis, and plots them on a coordinate plane. You can also add labels, titles, and customize the appearance of the graph using additional parameters.
Yes, you can plot multiple lines on the same graph in Matlab by using the "hold on" command. This allows you to add multiple plots to the same figure, making it easier to compare and analyze different data sets.
To save a graph as an image in Matlab, you can use the "saveas" function. This function takes in the figure handle and the desired file format (such as PNG or JPEG) as parameters, and saves the graph as an image file in the current working directory.
Yes, you can add a legend to a Matlab graph by using the "legend" function. This function takes in a cell array of strings as a parameter, with each string representing the label for a different line on the graph. You can also customize the placement, font, and other properties of the legend using additional parameters.
Yes, Matlab offers a variety of functions for creating different types of graphs, including bar graphs, pie charts, histograms, and more. These functions have different parameters and syntax, so it's important to refer to the Matlab documentation for specific instructions on how to create the desired type of graph.
