[jira] [Updated] (SYSTEMML-1150) Incorrect dimension mismatch when
indexing with loop-variable
[ https://issues.apache.org/jira/browse/SYSTEMML-1150?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Felix Schüler updated SYSTEMML-1150:
------------------------------------
Description:
{code}
A = matrix(2.0, rows=10, cols=10)
n = nrow(A)
s = 0.0
for (i in 1:n) {
# print("[i,1]: " + i)
s = s + as.scalar(A[i,1])
}
{code}
This code fails with the below exception. When uncommenting the print statement it works. Notice that the For-loop block is missing from the failing version.
Exception:
