1. How To Solve Showing ValueError: shapes (1,3) and (1,3) not aligned: 3 (dim 1) != 1 (dim 0) Error ?

To Solve Showing ValueError: shapes (1,3) and (1,3) not aligned: 3 (dim 1) != 1 (dim 0) Error The column of the first matrix and the row of the second matrix should be equal and the order should be like this only

2. Showing ValueError: shapes (1,3) and (1,3) not aligned: 3 (dim 1) != 1 (dim 0)

To Solve Showing ValueError: shapes (1,3) and (1,3) not aligned: 3 (dim 1) != 1 (dim 0) Error The column of the first matrix and the row of the second matrix should be equal and the order should be like this only

## Solution 1

By converting the matrix to array by using

```n12 = np.squeeze(np.asarray(n2))

X12 = np.squeeze(np.asarray(x1))
```

solved the issue.

## Solution 2

The column of the first matrix and the row of the second matrix should be equal and the order should be like this only

```column of first matrix = row of second matrix
```

and do not follow the below step

```row of first matrix  = column of second matrix
```

it will throw an error
