Cannot import data to matlab #91

Closed jochenkrattenmacher closed 6 years ago

jochenkrattenmacher commented 6 years ago

Hello!

When I try to open data with matlab (a simple table with one column, which has a header "x" and a dozen numerical values), a matlab error occurs:

Error using cell Size vector should be a row vector with real elements. Error in hashmaputils>loadhashmap (line 158) vector = cell(vector); Error in hashmaputils (line 45) [kIn, columnNames] = loadhashmap(input.filePath, input.data);

When I catch the error and try to view the value of the 'vector' variable, I see the following: Variable "vector" is inaccessible. When a variable appears on both sides of an assignment statement, the variable may become temporarily unavailable during processing.

I am using Matlab R2016b and Knime 3.5.3 (downloaded the matlab scripting extension within the GUI).
