What function is used to generate linearly spaced vectors in MATLAB?

The function used to generate linearly spaced vectors in MATLAB is linspace(). This function is specifically designed to create a vector that contains evenly spaced values between a specified starting and ending point. By providing the function with a start point, an endpoint, and an optional number of points, linspace() will return a vector of values that includes those endpoints.

For example, calling linspace(1, 10, 5) will produce the vector [1, 3.25, 5.5, 7.75, 10], which contains five equally spaced values from 1 to 10. This makes linspace() particularly useful for generating coordinates for plotting or creating discrete steps in simulations or numerical methods.

The other choices do not serve the purpose of generating linearly spaced vectors in MATLAB. Thus, the correct answer highlights the specific functionality of linspace() in this context.
