Subject Dimension mismatch exception
Date Thu, 20 Mar 2014 21:04:47 GMT
Dear all,

I am trying to compute the cosine similarity between several documents. I have an indexed
directory A made using 10000 files and another indexed directory B made using 20000 files.
All the indexed documents from both directories have the same length (100 sentences). I want
to get the cosine similarity between documents from directory A and documents from directory
B. I have used the code from here but on the two indexed directories. So I use something like
getCosineSimilarity(docs_A[i], docs_B[j]);

I get the following error:
Exception in thread "main" org.apache.commons.math3.exception.DimensionMismatchException:
44,375 != 596,263
    at org.apache.commons.math3.linear.RealVector.checkVectorDimensions(

    at NewApp.testCosine.getCosineSimilarity(

Please help me. Thank you very much!
