MATLAB: How to remove sample time color warning: “The model has 7 discrete rates, which is greater than the 6 discrete sample time colors available. The 6th and slower rates have been marked using the orange sample time color.”

Best Answer

To turn off the mentioned warning message, please run the following command from your MATLAB command window:

>> warning('off', 'Simulink:SampleTime:NoMoreSampleTimeColors')

Alternatively, to eliminate this warning, you can select 'Annotations' or 'Off' in 'Display->Sample Time-> Annotations/Off'. The warning is due to the number of colors in the Colors setup. Choosing 'Annotations' to display the sample time will solve the issue and you will have the same information available.

MATLAB: Specifying color data for patchm or patchesm

The "cdata" parameter of both the "patchm" and "patchesm" constructor expects to receive a singular color value, specified as either a color name (e.g. 'r' or 'red') or an RGB triplet (e.g. [1 0 0]). It will not take in a vector of color values that correspond to the different face colors.

Unlike "patch", providing a scalar value for "cdata" in the constructor for "patchm" or "patchesm" does not use the "CDataMapping" property to map into the colormap.

However, since "patchm" supports nearly all the properties that are supported by the "patch" function, we can color the faces by passing property name/property value pairs to the "patchm" function, as follows:

>> patchm(latData, lonData, 'FaceVertexCData', faceColors, 'FaceColor', 'flat')

This command will create a single patch with multiple faces, with the face colors specified by the array "faceColors". Specifics on the allowed formats of the array "faceColors" can be found on the Patch Properties documentation page, under the property "FaceVertexCData", linked here:

https://www.mathworks.com/help/matlab/ref/matlab.graphics.primitive.patch-properties.html

Since "patchesm" returns an array containing a separate patch object for each face, it is necessary to set the color of each of the patch objects individually to accomplish the same behavior.

For more information about these properties, please refer to the above link.

MATLAB: Discrete time simulations sampling rate question

The output for step size of 5 seconds and 0.005 seconds are the same. The only difference is that there should be enough simulation time to accomodate the whole simulation data given. For 0.005 seconds of step size, 60-80 seconds of stop time is sufficient, but for a step size of 5 seconds, a stop time of 5*20000 (20000 samples of data given) seconds is necessary for the entire signal to be shown up in the scope block. So, try changing the stop time to 100000 seconds in case of 5 second stepsize.

Hope it helps!
