Extract parts from two input vectors and glue them together to receive one vector.
[sim, out, num] = ld_vector_glue(sim, events, in1, fromindex1, toindex1, in2, fromindex2, toindex2, vecsize)
Output starting with in1 from fromindex1 until toindex1, continuing with in2 from fromindex2 until toindex2.
Index counting starts at 1
fromindex1 * - first index considered from in1
toindex1 * - stop cutting from in1 before toindex1. This means the value in1(toindex1) is not included
fromindex2 * - first index considered from in2
toindex2 * - stop cutting from in2 before toindex2. This means the value in2(toindex2) is not included
vecsize - size of each input vector. Vectors need to have equal size!
out * - as explained above. Size of output is (2*vecsize).
num * - number of values that have been glued together.
