Subscripted dimension mismatch error dec2hex
显示 更早的评论
Hello
I searched regarding this error but still could not resolve it. I am using the following code:
function[hexoutput] = hexaoutput(colordata)
[row col] = size(colordata);
hexoutput=zeros(row,col);
for i=1:row
for j=1:col
hexoutput(i,j) = dec2hex(colordata(i,j),6);
end
end
end
I am getting the subscripted dim mismatch error. But this is how we loop through a matrix. I am confused. Any help would be great. Thanks.

dec2hex(SOMETHING,6) is going to return 6 (or more) characters. You then try to store those 6 characters into a single numeric array location. Remember, hex is represented as character, but zeros() is numeric, so you are using the wrong datatype for your output array and you are not allowing for the fact that each output needs multiple characters.

Consider using sprintf('0x%06x', colordata(i,j))

The dec2hex(colordata(i,j),6) quantity is a string of at least six hex characters, and yet your are attempting to place it in a single element of hexoutput. It won't fit. You'll have to make hexoutput bigger! Maybe you'd like to make it three-dimensional.
