How to read txt files with variables in the file name?

Dear Matlab users,
Maybe someone can help me with the following:
For a project I have file names of the following form: abc@_def#_ghi$.txt where the @, # and $ are variables. These variables are known. E.g. the @-variable=[1 2 3 4 5], #-variable=[0.1 0.2 0.6] and $-variable=[40 50 60 70 80 90] (which makes 5*3*6=90 files in total).
If I would like to read the file with: @=1, #=0.6 and $=70, I use the following:
outcome=dlmread('abc1_def0.6_ghi70.txt','\t') %Note: \t, because columns are seperated by tabs
Now I would like to know how I can read these txt-files in the following way:
outcome=dlmread('abc@(1)_def#(3)_ghi$(4).txt','\t')
with: @(1)=1, #(3)=0.6 and $(4)=70.
In other words, I would like to use the vectors to define the name of the file. Is there a method to achieve this?
Thank you.

% Replace "p1, p2, p3" by smarter names...
p1 = [1 2 3 4 5];
p2 = [0.1 0.2 0.6];
p3 = [40 50 60 70 80 90];
for i1 = p1
for i2 = p2
for i3 = p3
filename = sprintf('abc%d_def%.1f_ghi%02d.txt', i1, i2, i3)
...
end
end
end
