initializing cell arrays

a=cell(dim)

Things to remember when using parfor

This website from matlab:
http://www.mathworks.com/help/distcomp/programming-considerations.html

-- cannot use clear inside the loop


specifically:

=========
Similarly, you cannot clear variables from a worker's workspace by executing clear inside a parfor statement:

parfor ii= 1:4
    <statements...>
    clear('X')  % cannot clear: transparency violation
    <statements...>
end

As a workaround, you can free up most of the memory used by a variable by setting its value to empty, presumably when it is no longer needed in your parfor statement:

parfor ii= 1:4
    <statements...>
    X = [];
    <statements...>
end

using nohup

nohup matlab -nodisplay -nosplash -r Script1 > out.txt &

Edit
f you want to run a function  with variables, this is how to do it:

nohup matlab -nodisplay -nosplash -r "funcitonabcc(var1,var2,..,varn); exit; " > out.txt &

the text within the double quotes needs to be written just as you would call commands in matlab.

Substringing in matlab

Many functions in matlab let you do various things to strings

strtok(s,delim)
returns the substring before delim

[first,rem]=strtok(s,delim)
first the substring before delim
rem the substring s-first(it includes delim)

strrep(s,'a','b')
replaces a with b in s
