Check if a variable has both a given type and size. Utility routine, but probably not very efficient if needed in a large loop. Syntax: >> ok = isa_size (var, check_size) >> ok = isa_size (var, check_size, check_type) Input: ------ var Variable to be checked check_size Required size of variable - the size of the array e.g. [2,3] or [1,1] or [4,5,100] - 'row' if a row vector of unspecified length - 'column' if a column vector of unspecified length - 'vector' if either a row or column vector check_type Matlab variable type to check against. In addition, will accept 'cellstr' (not a recognised keyword by the matlab intrinsic function 'isa', as it is not a class, but a special case of a cell) Output: -------- ok =true if var has desired type and size =false otherwise e.g. check if variable w is a 4x3 matrix of type double: >> ok = isa_size (w, [4,3], 'double') e.g. is variable w a row vector: >> ok = isa_size (w, [1,3], 'double')
