solve block

in response to A-ON advice, I have edited the worksheet. I would appreciate help from anyone.

Re: solve block

The variable ri is undefined.

It would have been better to attach a worksheet to a reply in the original discussion thread rather than posting it as a document. We can't attach worksheets to comments about a document.

Re: solve block

I sincerely ask for pardon. I hope you forgive my error.

However, i have discovered my mistaken. Thank you so much.

I am a new user to mathcad, still learning the rudiment of the program. please can you explain to me on what to do if I am to write a code (using iterative approach) rather than using solve block.

I would appreciate it alot.

Don't worry about it. I'm just giving you some advice about a better way to post questions. We can reply to a document in the comments, but we can't attach a corrected or example worksheet, which we can do in a discussion.

can you explain to me on what to do if I am to write a code (using iterative approach) rather than using solve block.

I guess the question has to be "why would you want to do that?".

Re: solve block

Thank you for your response. My aim was to use iterative approach ( using if, while statement etc) to solve the five equations with four unknown variables. severally, I have tried to write a simple program but seems not working before my friend asked me to use solve block.

Re: solve block

That doesn't really answer my question. Why would you want to write your own iterative routine rather than using a solve block? It's more work, and it would be much slower. Mathcad provides solve blocks so that you don't have to do that. You could certainly write such a routine in Mathcad, but it's not quite as simple as just using if and while statements (look up Newton's method for one of the simpler approaches)

Re: solve block

Thank you very much. Actually, my supervisor asked me to use iterative approach to develop the mathematical model. +

Re: solve block

A solve block is iterative, so you have done what was requested.

Re: solve block

Thank you once again for taking out time to respond to my request. More strength to your elbow.
