as a structural engineer, i deal with relatively simple mathematics, but with a high number of variables and assumptions during the design process.

i am looking for a handheld calculator which i can program with the different equations i use many times each day.

each equation has many variables, and many conditions. the best method of work for me is to use excel spreadsheets which i have built over the years(i use the "if" function and the "vlookup" function all the time)

i am not farmiliar with graphing calculators but am looking for a device into which i can program all these equations so i can take it with me to meetings and site visits so that i can evaluate on the spot

which graphing calculator will best suit my needs, and what programming language does it use

are there any handheld calculators which can be programmed in excel? or in MATLAB?
