matlab - Convert a cell of strings to a matrix of numbers -


i'm trying convert cell of numbers of different lengths matrix of numbers. i'm new matlab cells. apologize in advance if question sucks. i've done homework, last resort.

x cell of strings. want these strings converted numbers. there way convert cell matrix without brute force iteration?

i've tried cell2mat matlab freaks out. i've tried str2num matlab freaks out. i've googled "converting cell of strings matrix of numbers", nothing comes up.

here's cell:

>>x   x =  '0' '850' '10483' '16039' '25670' '31242' '37009' '41023' '46798' '51881' '61491' '67181' '72941' '76163' '85759' '96654' '102439' '104615' '114224'  >>class(x)  ans =  cell

you want str2double:

x = {'1';'12';'3.14'}; y = str2double(x)

which returns

y =       1.000000000000000    12.000000000000000     3.140000000000000

the reason mat2cell didn't work because numeric strings of different lengths. , str2num doesn't permit cell inputs. might read , doc str2num other reasons why str2double better anyways.

php - Calling a template part from a post -

i include iframe within post in wordpress. located inside content of post, meaning cannot in post template file, otherwise either before or after. i'd add facebook plugin within posts: <div id="socialwrap"><div class="fb-like" data-href="http://onlinearizonahomes.info" data-send="true" data-width="450" data-show-faces="true" data-font="arial"></div></div> i thinking of calling template part within post <?php get_template_part( 'social' ); ?> cannot use php within post without plugin (i'd avoid using plugin this). an alternative using javascript create html in post, seems unnecessary use of javascript. what best way add html within wordpress post? you can use shortcode. add functions.php function cudjex_fbshare( $atts, $content = null ) { global $post; $link = get_permalink($post->id); return '<div id="socialwrap...
