matlab代码为黄金比例持续分数(matlab code for golden ratio continued fraction)

我正在尝试编写一个Matlab函数来计算有多少项m,它需要黄金分数达到n位精度。 这是我到目前为止,但我一直得到0的输出。

phi = (1+sqrt(5))/2;
p=1;
p=[1+1/p];
LoopCounter = 0;
while (phi-p)>10^(-n)
    p=[1+1/p];
    LoopCounter = LoopCounter + 1;
end
m=LoopCounter;
m

我认为这对于那些研究数论或者刚刚开始学习Matlab的人来说是个常见问题。 任何建议? 谢谢!


I'm trying to write a Matlab function that computes how many terms, m, it takes the golden fraction to get to n digits of accuracy. Here is what I have so far, but I keep getting an output of 0.

phi = (1+sqrt(5))/2;
p=1;
p=[1+1/p];
LoopCounter = 0;
while (phi-p)>10^(-n)
    p=[1+1/p];
    LoopCounter = LoopCounter + 1;
end
m=LoopCounter;
m

I think this is a common question for those studying Number Theory or just starting to learn Matlab. Any advice? Thanks!

尝试:

public Cursor getBarcodeInfo(String number){

    // Safe check to make sure db and number is not null
    if(db == null || number == null){

         return null;
    }

    return db.rawQuery("select _id, barcode_item_name, barcode_measurement, barcode_unit from barcode where barcode_number = ?", new String[]{number});
}

try:

public Cursor getBarcodeInfo(String number){

    // Safe check to make sure db and number is not null
    if(db == null || number == null){

         return null;
    }

    return db.rawQuery("select _id, barcode_item_name, barcode_measurement, barcode_unit from barcode where barcode_number = ?", new String[]{number});
}
