Local sensitivity analysis with full normalizations in computational simulations for the coronavirus disease (COVID-19) using MATLAB, in this technique the set of parameters {k₁, k₂, k₃, k₄, k₅, k₆, k₇} are very sensitive compared to the other parameters thus two figures are computed, (a) the sensitivity of all variables with respect to all parameters, (b) the sensitivity of all variables with respect to the set of parameters {k₈, k₉, k₁₀, k₁₁, k₁₂, k₁₃}.
