stat

Get a quick summary of variable statistics in the command window.

I find this function useful for getting a quick idea about the range of values in a large multidimensional variable.
stat(variable) prints the following properties of a variable in the command window:

size: size of variable.
numel: number of elements in variable.
NaNs: number of not-a-number values in variable.
maximum: maximum value in variable across all dimensions.
minimum: minimum value in variable across all dimensions.
mean: mean value of variable across all dimensions.
median: median value of variable across all dimensions.
mode: most frequent value in variable across all dimensions.
std dev: standard deviation of variable across all dimensions.
variance: variance of variable across all dimensions.
