I'm currently using a MATLAB to work and I need some help:

I need to convert my output data (variable: units) be a double instead of a cell because I must perform a sum:

```
units = inputdlg(question,title);
sum = units + i;
```

I've tried this code also but didn't solve my problem:

```
units = double(inputdlg(question,title));
sum = units + i;
```

Someone could help me?

Answer:

`inputdlg`

returns a cell array of strings. You can convert to `double`

with `str2double`

:

```
units = str2double(inputdlg(question, title));
```
