Hi Jos,
As per my understanding, you are trying to initialize a matrix containing linear equations but are facing some errors, when you tried to initialize them differently.
In the first case, where there is a space before the minus sign, both "x" and "-y==0" are identified as separate elements by the compiler. So, the compiler tries to create a row matrix using those two elements. But the second row has only one term i.e., "x+y==0", making the dimensions of the matrix inconsistent. This is leading to the error saying, "CAT arguments dimensions not consistent".
Please have a look at the code below, for your reference:
eqns=[x -y==0]
The output of the above code is mentioned below, which indicates a row matrix:
eqns =
[x, -y == 0]
In all other cases, the compiler considers "x-y==0" as a single element, thereby creating a column matrix having the elements "x-y==0" and "x+y==0".
You can access the documentaion for “Matrices and arrays” here:
Hope this answer helps you.
Thanks,
Bhanu Prakash.
