2.2. Implementation Next, we will prepare a MATLABunction to calculate the specimen k. To do this, open the file named calc_ks.m and insert the k, equation that you just derived. You will notice that the derivative terms have already been supplied. Please use the same notation when writing your equation. Additionally, provide a value for k, as specified in the lab procedures. . IMPORTANT NOTE- You need to use these slopes variables below! didx1 (1): Top Section dTdx2 (2); Specimen dTdx3 (3); Botton Section YOUR CODE HERE Supply a value for k brass (from procedures) k.brass ???; %[W/(m C)] YOUR CODE HERE
