Counting the number of occurences of a specific (defined) sequence within a vector

I have a randon vector and I need to identify and count how many times a given sequence - at least 3 consecutive numbers, each larger than the other - occurs in the vector.

Then create a table with all indexes marking the start of the sequence and the lenght of the sequence

vector=randn(1,100);

Then I was thinking using some kind of for loop but ... I suck.

for i=lenght(vector)
    if vector(i)<vector(i+1)<vector(i+2)

I would download the excellent RunLength utility from the File Exchange, and then ...

d = diff(vector)>0;

[isInc,runLenTmp,startIndexTmp] = RunLength(d);

keepRun = isInc & runLenTmp>=3;

runLen = runLenTmp(keepRun) + 1;
startIndex = startIndexTmp(keepRun);
