回复： Variable Substitution in MathScript

[PeterTrollens]

Hi,

how is it possible in MathSkript to substitute a variable with the actual value in an expression?
To be more specific, I want to do in principle the following:

% this works
f='x+y'
ezsurf(f)

% then I want to multiply y by a factor
scale=100
f='x+y*scale'
ezsurf(f)
% which then fails.

Any advice is highly appreciated!

Thank you
Peter

Hi,

For ezsurf, it is unable to specify external variable. The workaround is that

1. Hardcode the variable with the actual value, e.g.

    f = 'x+y*100'

    ezsurf(f)

2. Format the input string for ezsurf, e.g.

    scale = 100

    f = sprintf('x+y*%f', scale)

    ezsurf(f)

Let me know your special requirement.
