I want to plot the following function
where a and b values are listed in the 1st and 2nd columns of an input file respectively, like this
a1 b1 a2 b2 a3 b3 ..... an bn
now I am plotting it using the following command
plot a1*exp(-0.001*(x-b1)**2) + a2*exp(-0.001*(x-b2)**2) + a1*exp(-0.001*(x-b3)**2) ...etc
what I need is a short command to plot all data without writing all the data one by one.
the expected output should be one continuous line like this
