Subject: [mg24854]  [mg24831] List of Interpolated functions inside plot




 If have defined the following interpolation for arbitrary integer m:

xyinterp[m_] := Interpolation[Table[{x, Sin[m x]}, {x, -5, 5, 0.25}]];

I can plot a number of the interpolated functions on one plot as follows:

Plot[ {xyinterp[1][x], xyinterp[2][x], xyinterp[3][x]}, {x,-5,5} ];

Let's say I want to plot a large number of the functions of integer m but I
like to use the Table command since typing can become quite tedious:

Then

Plot[ Table[xyinterp[m][x], {m, 1, 10, 3}],{x,-5,5} ]

doesn't work because the value of x needs to be defined pior to the
execution of the Table command. I have tried various forms of Hold but that
doesn't seem to work.

Any help or suggestions on how to make this work would be appreciated.

thanks,
Chris
