I have a very basic question to make.
Please review attached file defined to compute stress and deflection of simply supported beam.
The function for Bending moment, stress and deflection are defined with variable x which is defined over the length of beam.

All functions except deflection return right results except deflection. The value shown as a result with function x results incorrect results but when individual values of x is passed on to the function then the results are accurate.

I with to understand what seems to be the issue?

When an evaluation is performed for multiple values (inserted in a vector) you must perform element-by-element evaluation with the "vectorize" function. I also advise you not to use "x" either as a function variable or with vector containing the evaluation points
