copied!<p>I agree that matrix should be mainly used when working with numbers. The standard non-generic matrix type (which you can create using the <code>matrix</code> function) works with numbers of type <code>float</code>. If you want to work with other numeric types, you can use <code>Matrix.Generic</code> module, which contains functionality for working with generic matrices (containing any types).</p> <p>You can use generic matrix for storing tuples as well (if you want). A generic matrix can be created using the <code>ofList</code> function. You can also define a function for this to get a nicer syntax:</p> <pre><code>let anymatrix = Matrix.Generic.ofList let B = anymatrix [ [ [1,2]; [3,4] ]; [ [7,8]; [5,6] ] ] </code></pre> <p>To work with generic matrices, you can use the <code>Matrix.Generic</code> module: </p> <pre><code>let Bt = Matrix.Generic.transpose B </code></pre> <p>Typically, you'll use matrices only with numeric types, because many of the operations require some arithmetics in order to work. This will work for all basic numeric types (such as <code>int</code>) and you can also provide arithmetics for your own type using <code>GlobalAssociations</code> <a href="https://stackoverflow.com/questions/2225949/does-f-have-generic-arithmetic-support">discussed here</a>.</p> <p>However, if you want to simply store some values then there are other (more suitable) data types. You can also use <code>Array2D</code> which represents a mutable two-dimensional array.</p>
