How do you plot in Matlab?

plot( Y ) creates a 2-D line plot of the data in Y versus the index of each value.

2. If Y is a matrix, then the plot function plots the columns of Y versus their row number.

How do I read a file in Matlab?

Use fopen to open the file, specify the character encoding, and obtain the fileID value. When you finish reading, close the file by calling fclose(fileID) . A = fscanf( fileID , formatSpec , sizeA ) reads file data into an array, A , with dimensions, sizeA , and positions the file pointer after the last value read.

What is input () in Matlab?

x = input( prompt ) displays the text in prompt and waits for the user to input a value and press the Return key. The user can enter expressions, like pi/4 or rand(3) , and can use variables in the workspace. If the user presses the Return key without entering anything, then input returns an empty matrix.

Which is the input function?
