When this option is on, parameter comments are generated regardless of the number of parameters. This reduces the size of the generated file for models with a large number of parameters. When this option is off (the default), parameter comments are generated if less than 1000 parameters are declared. Parameter comments indicate parameter variable names and the names of source blocks. The Force generation of parameter comments option controls the generation of comments in the model parameter structure declaration in model _prm.h.

To inline these invariant constants, select Inline parameters. (See the Using Simulink manual for information on invariant constants.) In the above example, the two constants (1 and 2) and the gain value of 3 are invariant constants. Note that an invariant signal is not the same as an invariant constant. Given the model above, if both Inline parameters and Inline invariant signals is selected, the Real-time Workshop inlines the invariant signal S3 in the generated code. If you want to extract those points: aboveThreshold yourSignal (aboveThresholdIndexes) I leave it up to you to computer someThresholdValue because we dont know exactly what 'threshold based on the percentage of values in an array' means. The Inline invariant signals option is unavailable unless the Inline parameters option (on the Advanced page) is selected. Use the > operator: aboveThresholdIndexes yourSignal > someThresholdValue A logical vector. For example, the signal S3 in this block diagram is an invariant signal. If this option is selected, the MATLAB command window displays progress information during code generation compiler output is also made visible.Īn invariant signal is a block output signal that does not change during Simulink simulation.
See the Target Language Compiler Reference Guide for more information on loop rolling. Therefore the code generated for the Gain block iterates over the array in a for loop, as shown in the following code fragment.Ĭonst real_T *p_Gain_Gain = &rtP.Gain_Gain The size of the gain array exceeds the loop rolling threshold. The gain parameter of the Gain block is the vector myGainVec.Īssume that the loop rolling threshold value is set to the default, 5.Īn array of 10 elements, rtP.Gain_Gain is declared within the Parameters data structure, rtP. The loop rolling threshold determines when a wide signal or parameter should be wrapped into a for loop and when it should be generated as a separate statement for each element of the signal. If this option is selected, statements that were eliminated as the result of optimizations (such as parameter inlining) appear as comments in the generated code. These options are common to all target configurations. Code Generation and the Build Process (Real-Time Workshop User's Guide) Real-Time Workshop User's Guide
