# Problem 44950. Calculate Inner Product

Given two input matrices, x and y, check if their inner dimensions match.

• If they match, create an output variable z which contains the product of x and y
• Otherwise, z should contain a custom string message

Example:

```x = [1 2;3 4]
y = [5;6]
```

z = [17;39]

```x = [1 2 3;4 5 6]
y = [2 5;3 6]
```

z = "Have you checked the inner dimensions?"

OR

z = "The inner dimensions are 3 and 2. Matrix multiplication is not possible"

NOTE - An example of combining numbers and strings together is shown below:

```x = "The sum of " + 4 + " and " + 3 + " equals " + 7
```
```x =
```
`      "The sum of 4 and 3 equals 7"`
