DimensionMismatch

DimensionMismatch([msg])

The objects called do not have matching dimensionality. Optional argument msg is a descriptive error string.

Examples

1. Basic usage:

   julia> a = [1, 2, 3];
   julia> b = [4, 5];
   julia> c = [6, 7, 8];
   julia> DimensionMismatch(a, b)
   ERROR: DimensionMismatch: arrays could not be broadcast to a common size
   julia> DimensionMismatch(a, c)
   ERROR: DimensionMismatch: arrays could not be broadcast to a common size

   In these examples, DimensionMismatch is used to indicate that the arrays a and b, and a and c, respectively, cannot be broadcast to a common size due to a dimension mismatch.

2. Custom error message:

   julia> x = [1, 2];
   julia> y = [3, 4, 5];
   julia> DimensionMismatch("Custom error message: Arrays do not have matching dimensions.", x, y)
   ERROR: DimensionMismatch: Custom error message: Arrays do not have matching dimensions.

   Here, DimensionMismatch is used with a custom error message provided as the argument msg. It helps provide more descriptive information about the dimension mismatch between the arrays x and y.

Common mistake example:

julia> a = [1, 2, 3];
julia> b = [4, 5, 6];
julia> DimensionMismatch(a, b, "Mismatch between arrays")
ERROR: MethodError: no method matching DimensionMismatch(::Array{Int64,1}, ::Array{Int64,1}, ::String)

In this example, the third argument provided is a string, which is not a valid argument for DimensionMismatch. The third argument should be an optional descriptive error string, but it is not applicable in this context. Make sure to provide the correct arguments to DimensionMismatch.
