t1=rand(500,500);
t2=rand(500,500);
reshape(t1,500,500);
reshape(t2,500,500);
y=100sin(t10.3,0.6*t2);
n=imread(‘wood.jpg’);
sum=y+n;
figure,imshow(sum)


(eng.lamloom) #3

[SIZE=3]now sin is considered to be used as a noise with 2 dimensions added to an image i chosed 500*500 for t1 n t2 to match the size of the picture i have… i wrote the previous code but errors appeared as follows:
??? Error using ==> sin
Too many input arguments.

Error in ==> Untitled11 at 5
y=100sin(t10.3,t2*0.6);

??? Error using ==> plus
Class of operand is not supported.

Error in ==> Untitled11 at 7
sum=y+n;

please tell me how to fix these errors

[SIZE=4]شكل معادله ال [COLOR=Blue]y مش مفهوم بالنسبالي انت عاوز تعمل ايه

عموما جربها كده بس مش عارف ده اللي انت تقصده ولا لاء [/color]


y=100*sin([t1*0.3,0.6*t2]);
