Hello, does anyone know how I can change the symbolic output in Matlab so that matlab exactly matches my input? Currently, Matlab defines new "variables" to shorten the output.

I don't want the

substitution

You may use sympref function with 'AbbreviateOutput' parameter set to false to avoid the creation of new variables

sympref('AbbreviateOutput',false);
syms K EI l1
K1 = [12*EI/l1^3, 6*EI/l1^2, -12*EI/l1^3, 6*EI/l1^2;
       6*EI/l1^2, 4*EI/l1, -6*EI/l1^2, 2*EI/l1;
      -12*EI/l1^3, -6*EI/l1^2, 12*EI/l1^3, -6*EI/l1^2;
      6*EI/l1^2, 2*EI/l1, -6*EI/l1^2, 4*EI/l1;]
