Simulink: minimum values in vector segments
2 views (last 30 days)

In Simulink I have a vector, whose elements can be considered as groups. I need to find the minimum value of each group.
For example I have a vector of 20 elements, which can be devided in five segments of four elements each. The result should be a vector of five minimum values (one for each segment). The exact length of the vector and the number of segments are defined by workspace variables and are constant at runtime.
The equivalent matlab code would be this:
for segment = 1:n_segments
segment_length = n_input_elements/n_segments;
result(segment) = min( inputvector(1+(segment-1)*segment_length : 1+segment*segment_length) );
end
I did not manage to use the MinMax block (together with a selector block) to achieve the desired behaviour. Do you have any suggestions how to implement this?
Best regards

Use a MATLAB Function block and code similar like this: y=min(reshape(1:20,4,5))
work out the warnings and errors regarding variable size of the data
