# [✓] Plot the values of a column-matrix against each of its rows?

GROUPS:
 Dear friends, I ask your help, please. After some calculations, I got the matrix z and its inverse. After the multiplication of the inverse of z by the column matrix [1, 1, 1,1...1], I would like to plot the resulting S values against its row ( k, from 1 to 20). How can I do this , please ?? The command I have tried simply does not work. Scabral S = (Inverse[z]).{{1.0}, {1.0}, {1.0}, {1.0}, {1.0}, {1.0}, {1.0}, {1.0}, \ {1.0}, {1.0}, {1.0}, {1.0}, {1.0}, {1.0}, {1.0}, {1.0}, {1.0}, {1.0}, \ {1.0}, {1.0}}; For [k = 1, k < 21, k++, Plot[k, Abs[S[[k]]]]] (IT DOES NOT WORK!!) 
 Bill Simpson 1 Vote Without knowing anything about an example Inverse[z] it may be difficult to answer your question correctly.Does this work? ListPlot[Table[Flatten[{k, Abs[S[[k]]]}], {k, 1, 20}]] If that isn't what you are looking for then if you provide some information about what Inverse[z] contains then might help.A description of what you would like the plot to look like might also help.
