各位大大好，小弟我最近因為要用不定積分。所以上網google了一下，必須要用到syms這個指令。但是我在help裡面打上他的Example卻無法執行，出現以下錯誤。麻煩了解的大大幫我確認一下QQ PS: 我是使用學校授權版本以下是我的CODE syms x f(x) = [x x^2; x^3 x^4]; f(2) 以下是錯誤訊息 Error using sym License checkout failed. License Manager Error -101 All licenses are reserved for others. The system administrator has reserved all the licenses for others. Reservations are made in the options file. The license server system must be restarted for options file changes to take effect.
