如何实现用户输入可变参数

以下是灰度变换为伪彩色代码 如何实现用户可变参数

clc
clear
close all
gray1=imread('D:\Miss.bmp');
subplot(131);
imshow(gray1);
title('原始图像');
gray=double(gray1)/255;
for i=1:256
    for j=1:256
   
            rgb(i,j,1)=abs(sin(0.3*gray(i,j)));     %红色变换
            rgb(i,j,2)=abs(sin(1.2*gray(i,j)));     %绿色变换
            rgb(i,j,3)=abs(sin(0.3*gray(i,j)+0.3)); %蓝色变换
      
         
    end
end
imwrite(rgb,'colorimage.bmp');
rgb=imread('colorimage.bmp');
subplot(132);
imshow(rgb);
title('伪彩色增强图象');
for i=1:256
    for j=1:256
   
            rgb1(i,j,1)=abs(sin(1.3*gray(i,j)));     %红色变换
            rgb1(i,j,2)=abs(sin(1.3*gray(i,j)));     %绿色变换
            rgb1(i,j,3)=abs(sin(1.3*gray(i,j))); %蓝色变换
      
        end
    end
end
imwrite(rgb1,'colorimage1.bmp');
rgb1=imread('colorimage1.bmp');
subplot(133);
imshow(rgb1);
title('RGB分量相同图象');
