If i has supply=0.2x + 20 and p=RandData(1,:) is there a way to substitute p in for x?

If i has supply=0.2x + 20 and p=RandData(1,:) is there a way to substitute p in for x?

[Elliott Cameron]

to make it clear i would like a new equation called t=0.2p+20

[darova]

what about subs?

syms s p
supply = 0.2*x + 20;
new_supply = subs(supply,x,p);

[Elliott Cameron]

is there a way without using syms?

[Elliott Cameron]

or to then remove the syms after?

[darova]

You can clear sym variables after

clear x p

Hi,

If you have to define “supply” in terms of “x” initially then you can substitute “p” in place of “x” by using “syms” as follows:

syms x 
supply=0.2*x + 20 ; 
p=RandData(1,:); % As per your code
out = subs(supply, p); 
clear x; 

Otherwise you can define “p" and then define "supply" in terms of "p" as follows:

p=RandData(1,:); 
supply=0.2*p + 20 ;
