Start Hunting!This yields G as a symbolic sum but I need it as numeric sum. I tried it using symsum function but that too yields a symbolic answer. Using, subs function for t=1 won't change it into a numeric value. Any help would be highly appriciated.Update this solution may not be faster under Matlab, because the execution engine can optimise the loops in the original code. (It does provide a speedup under Octave.) One trick to deal with if statements within loops is to turn the if statement (or part of it) into a logical matrix. You can then multiply the logical matrix elementwise by the matrix of values you are adding in each step.Aug 12, 2021 · 本回答被题主和专家选为最佳回答 , 对您是否有帮助呢? 报告相同问题？.
