clear all;
table = readtable ('data_part1.xlsx', 'Range', 'A1:E13')
sigma = table. (3) (1:12);
energy = table. (4) (1:12);
C12 = 4 * energy .* sigma.^12;
C6 = 4 * energy .* sigma.^6;
r = linspace (sigma * 0.95, sigma * 2.5, 12)
data has been imported from an excel spreadsheet hence the references, unsure of how to get rid of this error message on the last line of code? (0.95 and 2.5 are my min and max respectively)

You define sigma as a vector (12 numbers). In linspace, your input is sigma multiplied by 0.95 or 2.5. This only scales the values in your vector. The inputs are still vectors. However, they must be scalars (one number).
% Valid syntax
linspace(0,5,10)
% Incorrect syntax
linspace([0:5],[20:25],12)
