Insufficient number of input parameters.

function calculate_gain_sfunc(block)

setup(block);

end

function setup(block)

% Register the number of ports

block.NumInputPorts = 3; % Q1, Q2, and F2(t)

block.NumOutputPorts = 2; % y1 and y2

% Set up the input and output ports

block.SetPreCompInpPortInfoToDynamic;

block.SetPreCompOutPortInfoToDynamic;

block.InputPort(1).Dimensions = 1; % Q1

block.InputPort(2).Dimensions = 1; % Q2

block.InputPort(3).Dimensions = 1; % F2

block.OutputPort(1).Dimensions = 1; % y1

block.OutputPort(2).Dimensions = 1; % y2

% Register the parameters

block.NumDialogPrms = 9; % J1, L1, R1, AE, F1, J2, L2, R2

% Set the sample time

block.SampleTimes = [0 0];

% Specify the block simStateCompliance

block.SimStateCompliance = 'DefaultSimState';

% Register the methods

block.RegBlockMethod('Outputs', @Output); % Register the output method

end

function Output(block)

% Get the inputs

Q1 = block.InputPort(1).Data;

Q2 = block.InputPort(2).Data;

F2 = block.InputPort(3).Data;

% Get the parameters

J1 = block.DialogPrm(1).Data;

L1 = block.DialogPrm(2).Data;

R1 = block.DialogPrm(3).Data;

AE = block.DialogPrm(4).Data;

F1 = block.DialogPrm(5).Data;

J2 = block.DialogPrm(6).Data;

L2 = block.DialogPrm(7).Data;

R2 = block.DialogPrm(8).Data;

% Compute the gains

gain1 = J1 * L1 / (R1 * (AE - F1));

gain2 = J2 * L2 / (R2 * (F2 - AE));

% Compute the outputs

y1 = gain1 * Q1;

y2 = gain2 * Q2;

% Set the outputs

block.OutputPort(1).Data = y1;

block.OutputPort(2).Data = y2;

运行结果：

calculate_gain_sfunc

输入参数的数目不足。

出错 calculate_gain_sfunc (line 2)

setup(block);

The calculate_gain_sfunc requires an input. You called it without any inputs.

calculate_gain_sfunc  % WRONG way to run the function
calculate_gain_sfunc(block) % CORRECT
