May I ask which document is the least squares reference in the method option of the c2d function?

I pay more attention to which document the texture is referred to

Hi @xue li,

I understand that you would like to get more information on the “least-square” option of the “c2d” function.

The c2d function in MATLAB converts a continuous-time dynamic system to discrete time. It has several discretization methods including ‘least-squares.’ The ‘least-squares’ method is used for SISO (Single Input Single Output) systems only. It minimizes the error between the frequency responses of the continuous and discrete systems by least-squares minimization.

For more information, you can refer to the following documentation page:Continuous-Discrete Conversion Methods - MATLAB & Simulink - MathWorks India

Hope this addresses your question!
