Octave is looking for a variable named "CTL[etc]" and trying to evaluate it; no
such variable exists so it throws an error.

You want:

my_matrix = dlmread('CTL0125B_B34C11_325_HP_2to40mA_MA_Retrial2.dat')

Note the quote marks that set off a string rather than a variable (a string
refering to the filename).  Note also the "my_matrix = " on the left side -- you
need to assign the results of dlmread somewhere.

Now you can use my_matrix to do analysis with (assuming you didn't need to
specify custom delimiters in dlmread).
