Automaticlly converting negative values to 0
显示 更早的评论
Hey. This is my code.
Ex_UpperBar * Ey_UpperBar * image(x_LowerBar,y_LowerBar)
Ex_UpperBar * Ey_UpperBar
ans =
-1
image(x_LowerBar,y_LowerBar)
ans =
uint8
89
but it is giving the Answer:
Ex_UpperBar*Ey_UpperBar*image(x_LowerBar,y_LowerBar)
ans =
uint8
0
It is supposed to return -89. How do i fix it? Thanks

Use a command int8() or int16() to store your processed data that resolves your task. e.g.: a= -89; b=int8(a)

uint8 cannot store -89 and thus, 0
Thus, store your data in int8 or better int16.

int16(Ex_UpperBar)*int16(Ey_UpperBar)*int16(image(x_LowerBar,y_LowerBar))
