Script to create in a bash script

Here is a shell script I use to create multiple nohup commands and put them in bash script called scripts1to100.txt. Each nohup command runs a matlab function called  runFunctionWithVariablesAandB which takes a and b as inputs.

for i in {1..100};
 do
let a=(i-1)*100+1;
let b=i*100;
echo nohup matlab -nodisplay -nosplash -r \"runFunctionWithVariablesAandB\($a:$b\)\; exit\;\" \> \/home\/logs\/batch$i.log \& >>scriptsFor1to100.txt;
 done

Once script1to100.txt is ready, you can run it by calling 'bash script1to100.txt'

Note: This particular script launches 100 parallel runs of runFunctionWithVariablesAandB, each with a different set of inputs.

To check if stuct S has a field called 'fieldName', use:

isfield(S, 'fieldname')

Changes to run BING (objectness)

General changes to run on our servers:
-- In the objectness folder: change line 15:
from
set(OPENMP_FLAG "-fopenmp -std=c++11 -ftree-vectorize")
to
set(OPENMP_FLAG "-fopenmp -std=c++0x -ftree-vectorize")
--Put absolute path to the dataset as opposed to relativepath in Main.cpp


Specific changes to make it compaible with ImageNet:
in Objectness/CmFile.cpp line number: added these lines:
415                                     if (line.find (' ') != string::npos)
416                                     {
417                                       int position = line.find (' ');
418                                       strs.push_back(line.substr(0,position));
419                                     }
420                                       else
421                                       strs.push_back(line);

The changes in everything above xml file issues can be ignored
