Summary: Missing indexing hop size reset on negative reconcile after loops Key: SYSTEMML-2340 URL: https://issues.apache.org/jira/browse/SYSTEMML-2340 Project: SystemML Issue Type: Bug Reporter: Matthias Boehm The below script incorrectly returns 100 instead of 98. Although the difference is detected during reconciliation after size propagation through the loop, the indexing hop current does not allow for size reset and thus the correction pass is ineffective here. {code} X = rand(rows=100, cols=1); Y = X # two loop iterationn -> nrow(X)=98 for( i in seq(1,2,1) ) { n1 = nrow(Y) + 0.0; Y = Y[2:n1,] - Y[1:n1-1,]; } print(nrow(Y)); {code} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
