Function to scale image
显示 更早的评论
Could someone kindly point out the syntax/ other error which is preventing my function to scale image from running properly?
function [scaledimage] = scalefunc(img, value)
scaledimage = value*img; %ensures that multiplication occurs element wise;
end
This is the output I am currently getting-
Not enough input arguments.
Error in scale (line 2)
scaledimage = value*img; %ensures that multiplication occurs element wise

How did you call the function? I assume you didn't pass input arguments
It must be called with input arguments, like
[scaledimage] = scalefunc('Image.jpg', 10)

Can you attach the screenshot of your function call and error message?

Shift these lines to the above of function definition
img = imread('family.png');
imshow(scaledfunc(img, 10))
Currently, your file is a function and expects all statements to be inside function. Change it to a script by making above change
