Hello! How do I modify the above code so that only the five equation objects with matching y's and x's are created: eq_y1_x1, eq_y2_x2,eq_y3_x3,eq_y4_x4,eq_y5_x5? Thanks!

Code: Select all

	equation eq_{!i}.ls y{!i} c x{!i}

Thank you. But what if the series names are xa, xb, xc, xd, xe and ya, yb, yc, yd, ye?

Hello,

You could loop over the common suffix of the x? and y? series, e.g.

Code: Select all


for %s a b c d e
    equation eq_y{%s}_x{%s}.ls y{%s} c x{%s}
next

Similarly named objects let you write terse loops, but can always explicitly list all the names and loop over groups of those elements, e.g.

Code: Select all


for %y %x ya xa yb xb yc xc yd xd ye xe
    equation eq_{%y}_{%x}.ls {%y} c {%x}
next
