What’s the “Dimensions of Arrays Being Concatenated should not Constant” Error in MATLAB
This error message in MATLAB signifies that the arrays you are attempting to concatenate have incompatible sizes. MATLAB requires that arrays being concatenated should have constant dimensions alongside the concatenation axis. An occasion illustrating this error is when the next code is executed:
X = [6 8 2];
Y = [9 4 1 3];
Z = [X; Y];
The array X has dimensions 1×3, whereas the array Y has dimensions 1×4. Therefore, because of their various dimensions, the arrays X and Y are unable to be concatenated collectively.
Easy methods to Repair – Dimensions of arrays being concatenated should not constant in MATLAB
To repair the error, that you must make it possible for the arrays that you’re attempting to concatenate have the identical dimensions. You are able to do this by resizing the arrays or through the use of the cat() perform to concatenate the arrays alongside a particular dimension. Now the code has the 2 arrays having the identical dimension which can make this error go away:
X = [6 8 2];
Y = [9 4 1];
Z = cat(1, X, Y);
To concatenate the arrays X and Y alongside the primary dimension, you’ll be able to make use of the cat() perform. Which means that the ensuing array Z may have dimensions 2×3.
A number of extra components can result in the incidence of the “Dimensions of arrays being concatenated should not constant” error.
- When you try to concatenate an array with a scalar, an error will come up since scalars can’t be concatenated with arrays.
- When trying to concatenate an array with a cell array, an error will happen since cell arrays can’t be concatenated with arrays.
Conclusion
Resolving the “Dimensions of Arrays Being Concatenated should not Constant” error in MATLAB includes guaranteeing that the arrays you are attempting to concatenate have appropriate dimensions. By verifying array dimensions, reshaping arrays if needed, reallocating arrays, and utilizing conditional concatenation, you’ll be able to overcome this error successfully.
