Polynomial类Objective-C实现多项式算法示例

Polynomial.h文件：

#import 
   
    @interface Polynomial : NSObject@property (nonatomic, strong) NSMutableArray *coefficients;@end
   

Polynomial.m文件：

@implementation Polynomial- (id)init {    self = [NSObject new];    self.coefficients = [NSMutableArray new];    return self;}- (void)addTerm:(double)term {    [self.coefficients addObject:term];}- (void)removeTerm:(double)term {    [self.coefficients removeObject:term];}- (void)multiplyByPolynomial:(Polynomial *)anotherPolynomial {    NSMutableArray *newCoefficients = [NSMutableArray new];    for (double coefficient : self.coefficients) {        for (double anotherCoefficient : anotherPolynomial.coefficients) {            [newCoefficients addObject:coefficient * anotherCoefficient];        }    }    self.coefficients = newCoefficients;}- (double)evaluateAtX:(double)x {    double result = 0.0;    for (double coefficient : self.coefficients) {        result += coefficient * pow(x, [self.degree]);        [self.coefficients removeObject:0.0]; // 移除零项    }    return result;}- (int)degree {    return [self.coefficients count] - 1;}

Polynomial类实现了多项式的基本操作，包括：

通过这种方式，我们可以创建一个多项式对象，并通过上述方法进行操作。这个实现简化了多项式运算，使其易于使用和扩展。
