how to plot graph from table or from excel in Mathcad ?
i cha,ged pre with vol but i found th problem in the picture. how to remove the line and the area indicated in the
I am currently working on MATHCAD 15. It applied the same steps, but the following message appears:
this value must be real, how to set it, ( attached file ).
The reason for the error is that pre is a nested matrix. Its element #14 is not a scalar but a 15x1vector.
The reason for this is that p is nested, its element #2 is a 15x1 vector
The reason for this is that epsilon is nested, its element #2 is a 15x1 vector
Haven't traced any further back.
This was subtle.
in your sheet epsilon[2 set the element 2 of epsilon to a 15,1 matrix
in attached sheet I have got around this and given more points on the curves.
