要将C MEX S-Function合并到模型中,请从Simulink 库浏览器中拖动 S-Function模块。同样,要将 2 级 MATLAB S-Function合并到模型中,请将 2 级 MATLAB S-Function模块拖到模型中。 打开“模块参数”对话框,并在“S-Function名称”字段中指定S-Function名称,以便为 S-Function模块提供功能。例如,键入 timestwo ...
MATLAB显示 错误使用 fmincon Nonlinear constraint function must return two outputs; the nonlinear inequality constraints and the nonlinear equality constraints. 这个错误是由于使用fmincon函数时,非线性约束函数的输出不符合要求导致的。在MATLAB中,非线性约束函数需要返回两个输出:非线性不等式约束和非线性等式约束。
% Create "short hand" for the cost function to be minimized costFunction = @(p) nnCostFunction(p, input_layer_size, hidden_layer_size, num_labels, X, y, lambda); % Now, costFunction is a function that takes in only one argument (the % neural network parameters) [nn_params, ~] =...

How to Create a MATLAB Function (9:01) Functions with Multiple Inputs or Outputs (3:22) Function Argument Validation Write functions with multiple inputs and outputs (top). Use function argument validation to make functions more robust (bottom).Use...
Define the function inputs and outputs by editing the function declaration statement: function[mean, stdev] = stats(vals) This statement defines a function calledstatswith three variables. The statement defines an input argument,vals, and two output arguments,meanandstdev. ...
The functionimshowcan also be accompanied by a two-element vector[low high]with which the user specifies the display range of the grey-scale image. If this vector is left empty[], the minimum and maximum grey-scale values of the image are displayed as black and white pixels, respectively,...
In most cases,groupsummaryis the recommended function for grouped calculations. It is simple to use and returns a table with labels that describe results. The other listed functions, however, also offer capabilities that can be useful in some situations. ...
Ourmin_and_maxfunction takes in an array that we'll callx, finds the minimum and maximum, and stores the two results in an output array. Clear? Good. But now let's make it more difficult. Theminandmaxfunctions both returntwooutputs if desired (both the minimum or maximumandthe index ...
