How to get Matlab to calculate answers from linspace

Hi, I want to calculate the temp change from years 1 to 5; however I keep getting nothing when I run the code. Would appreciate any help.

T0 = 473.15; %initial temp
r = 10; %cooling in C per year
t = linspace(0,5,1); %trying to find temp change from years 1-5 for each year
T = T0-r.*t; %equation

You have

linspace(0,5,1)

linspace(A, B, C) requests that you take a total of C point starting from A and ending at B (inclusive in both cases.) So you are asking for there to be only 1 point.

If you want integer year numbers use 1:5
