How it into the matrix ??

[Athur]

Hi. I want Formula into the matrix. thanks

N(x) only has one column, so it's a vector. There is no need for a column selector. However, if you must have a column selector here then, because Mathcad starts counting at zero, you must use <0> not <1>.

Here you are trying to use the column selector (Ctrl_Shift_C) to select rows. You need to use the row selector (Ctrl_Shift_R) for this. However, Harvey's method is much better when selecting a single value from a vector.

You created N(x) using a range variable x. Therefore, N(x) is a range variable too. You can not refer to a single element of a range variable.

Create x as a vector. Then create N(y) as a function of a single value. N(y):=R*b*y. Then you can pick any element of the vector x to use for the argument. e.g.

N(x[0) for first element of x. [ is the subscript operator

Thank Harvey Hensley.

I have done. verry good.

THank agian.

The index of variables (vectors) must be integer!

Describe please with words not with Mathcad-operators that you want to do.

Something like the following:

thank you .

A very good way of doing

[HarveyHensley]

I'm glad you liked it. Now, please tell me what software you used to annotate your screen shots with red rectangles, arrows, and text?

[ELSID]

Looks like he PDF'd his file and added the annotation to the PDF via a PDF program like Adobe, Foxit, etc.

[MikeArmstrong]

Yes correct. I use Acrobat for similar marking of documents.
