how t o use equation coming out of solve function with an array

I'm trying to put a simple array into a function and plot the values that comes out, i think it doesn't work cause the array size of the function that comes out is not equal to the array size of ti , im kinda new to matlab so sry if this is a noob question

syms toFx
syms ti

ti=1:1:20

toFx=solve(ti./toFx==13,toFx)

plot(ti,toFx)

Answer 1

[Walter Roberson]

ti=1:1:20

toFx=solve(ti./toFx==13,toFx)

is asking to find one single toFx that satisfies all 20 of the equations simultaneously.

syms toFx
syms ti

ti_vals=1:1:20

toFx=solve(ti./toFx==13,toFx)

plot(ti_vals, subs(toFx, ti, ti_vals))

i doubted that this was whats happening 5 mins ago but i still couldn't find another way to do it , thanks!

The main alternative would be to use a loop.
