Hi,
is there a matlab function that computes the highest frequency of occurences? for example: A=[3423 3420 3423 3421 3423 3523 3524 3545 3644 3999]; how can i get as an answer 3423 since it occurs the most?
MATLAB: Highest frequency
find

The issue is just in plotting. Straight lines between two points aren't straight on a semilog plot. When you just plot the endpoints, the graph connects them with a straight line, but that's gives the wrong impression of what is going on. Try this, and plot the intermediate points on the line to verify what is going on:
