Goodmorning,
Which block should be used to write to a specific index of an array in Simulink.
Eg. I have a signal with an array [2, 1, 8, 5] and I want to write a 2 to index 3, keeping the other values equal. This should result in an array [2,1,3,5].
Should this really be done by a matlab function?

I s there really no 'inverse' block to the "Index Vector" block??
Seems like quite an oversight on behalf of simulink functionality?

Use Assignment block.
OR
Split the array signal using Demux. Then connect the all (except desired index to change) outputs to Mux. Connect other signal at desired index.
