An expression exists that is equivalent to a : b : c : d. Although MATLAB will execute the code, it is unlikely to return your intended results.

For example, suppose your code is this:

a:b+c:d+a:b

Due to operator precedence rules, MATLAB processes the code as though you specified parenthesis, like this:

a:(b+c):(d+a):b

Rewrite the code to remove one or more of the colons.
