我在Maxima中有一个矩阵,可以说(为简化问题):

A:矩阵([2 *(a ^ 2 + b ^ 2 + c ^ 2)])

但是我知道:

a ^ 2 + b ^ 2 + c ^ 2 = 1

为了获得A = [2],如何根据该方程式简化Maxima中的矩阵?

我找到了解决方法:

A: matrix([2*(a^2+b^2+c^2)]); eq: a^2+b^2+c^2 = 1; scsimp(A, eq);

答案 1 :(得分:0)

您可以使用Command

package loopturn.loanbot.main;

import net.dv8tion.jda.api.events.message.guild.GuildMessageReceivedEvent;
import net.dv8tion.jda.api.hooks.ListenerAdapter;

public class Command extends ListenerAdapter implements CommandInterface {

    private String command;
    private CommandExecutor executor;

    public Command(String command, CommandExecutor executor) {
        this.command = command;
        this.executor = executor;
    }

    public Boolean onCommand() {
        return null;
    }

    public void onGuildMessageReceived(GuildMessageReceivedEvent event) {
        String[] messageSplitBySpace = event.getMessage().getContentRaw().split(" ");

        if(messageSplitBySpace[0].startsWith("!")) {
            if(messageSplitBySpace[0].equalsIgnoreCase("!" + command)) {
                executor.onCall(event);
            }
        }
    }

}
