how to solve 'Error using | MatrixMatrix, dimensions must agree. ' ? here is my code
clc; clear all;
T=0:0.001:0.07;
size(T);
cm=1.;
lo=-3.545-0.833*log(100*cm)-(9601.-2368.*log(100.*cm))/(T-195.7-32.25*log(100.*cm))
figure();
plot(T, lo, 'DisplayName','T=700000')

Read about MATLAB element by element operations. You are dividing two arrays, you need to divide element by element.

You have used mrdivide not normal division here.
correct one is
clc; clear all;
T=0:0.001:0.07;
size(T);
cm=1.;
lo=-3.545-0.833*log(100*cm)-(9601.-2368.*log(100.*cm))./(T-195.7-32.25*log(100.*cm)); % division by element
figure();
plot(T, lo, 'DisplayName','T=700000')
